bro not gonna lie, I just graduated with a bachelors in Physics and I'm going to need to watch this a few times to understand what the helk he is talking about.
I feel like this may be the best explanation of torque in the history of man and I also feel like I still may need to watch it 20 times to even grasp the basics of it.
I just realized how much I love the set of this video. It’s a whole ass kitchen for some reason but instead of cookware there’s calipers, forced induction, and an inner cooler. It’s like a cooking show but instead of food he’s cooking info for my brain and the food is cars
smh if you google this you get "horsepowah is how fast you go when you hit the wall and torque is how far the wall goes" which not only does not make sense it also confuses the fuck out of you
Because that's how Google's algorithm works. Whatever people search the most, that's what you get the first in the search result. Best is to go until the third page, you'll find whatever you're looking for within the first 3 pages. Anything beyond and your lurking into the dark web. Probably find how Torque and horsepower are made up by members of Illuminati and how it was used to enslave an extinct human race we dont know about. XD
Except that he gets all kinds of things wrong. 1) Stroke has no effect on torque. On the power stroke, the peak torque at the halfway point of the stroke might be higher, but the average torque will be the same, because more torque is being transferred to the crankshaft during other parts of the power stroke (near TDC and BDC). 2) Work is just when you move something through the application of force, it doesn't describe the rate at which it is moved. Power describes the rate of work. 3) Inertia dynos measure power directly and then calculate torque from the power curve. They can do this because they're measuring how quickly the engine is accelerating a flywheel. They're measuring the rate of work, in other words. 4) Diesels don't make more torque than gasoline engines unless they're boosted higher. Compare the Mercedes OM604 engines to the Honda F20A or F20B engines, or the naturally aspirated Detroit 6.2 or 6.5 diesel to the GM 350, or the LS1. 5) Diesel revs are limited because diesel fuel burns so much more slowly than gasoline, the piston starts moving faster than the flame front at high rpm.
Great video! I'm a french Engineer, and a scientist (a real one). Trying to find videos as an answer to friends, i've looked at a lots of youtube videos explaining torque vs horsepower: they where all wrong and full of mistakes. Most of them where made by people that obviously didn't understand the difference, and that actually only spoke of torque and gearbox (torque converters). Your video is the first one i find that finally tells the truth, about "work" and about time, and that tries to explains what it really means. Well, i was expected the last step that would include energy in the explanation, but your video is already great.
@@jonmiller6633 For modern Renault, i can only agree, but not sure a significant part of them are still "invented" in france by real french engineer. If you want to see something really french-made, you may rather look at Ariane-4 space program. And the 5 is junk because it was made with america. (By the way, in the years 1960 and 1970, renault cars where "ok", and very reliable, because "invented" by real french engineers.) (Ugly but reliable). Anyway, my car is of curse 100% japanese :-p. Planned obsolescence or even programmed failure is the new rule with french cars, and these planned failures are often precisely designed. At the same time as my engineering school, i also graduated from an (english-style) business school. They taught us Planned Failure, in a topic called "quality management", and in a very specious way: they spent a huge part of this topic warning us against what they called the "over-quality" mistake. As for american people, they have a "blur", fuzzy, imprecise way of talking. In this video, when he says "force", in that sentence, it's in the "muscular" way american people use that word, same as actively forcing with your muscles, actually meaning "using energy", or in the end, "power". And yes, this way of talking is confusing when you already know what this is all about. As a scientist, of curse, it's not possible to mistake power for force. But that's not helping ordinary people to see how this "gets real" in a car. And no, just writing a formula does not mean you understand why physics works.
@@microtalksquantumleap yes, it's correct. the only difference between "work" and "horse power" is that: * in "work", you apply the "duration" twice. * in "horse power", you apply the "duration" three times. "work" is in Joules and is [W] = (M x L x L ) / (T x T) "horse power" is in Watts and is [W] = (M x L x L ) / (T x T x T) (dimentions of units is just another way to "see" the nature of each "thing" that we mesure in physics), but to really understand what is what, this video from Donuts is perfect.
Over steer: you hit the fence with the back end of your car Under steer: you hit the fence with the nose of your car Horsepower: how hard you hit the fence Torque: how far you take the fence with you Done.
If you don't have basic mechanics (I'm talking physics mechanics, not car mechanics) down this video will be really hard to understand. To truly understand it study up on torques/moments, work/energy and forces. A little bit of basic calculus and really basic trigonometry also helps. There is a lot here and these guys did a good job of trying to simplify a very complex topic.
@@aluncoch Yep, because you have understand each concept (torque, work speed...) and then understanding the relationship between them and how they effect each other.
@@humanbeing4109 i understood it. Even i'm not a mechanic. But it took me a lot of thinking just to understand it. When i finally understood, i realized there could have been an easier demonstration
Torque is power the house power gives torque it’s power. Or else the Torque do nothing without the horse power. You turning the torque wrench is giving it it’s power
Yay, somebody gets it! (only saying because of all the folks who obviously didn't pay attention in High School Physics, this is from a high school physics teacher)
@pyropulse yes but u have to convert almost everything back to si unites, where in matric u already have them in kg, liters, meter etc. It just makes the whole thing simpler and easier to understand, especially for countries who have studied and uses matric system which is most of the world, bc it MAKES FUCKING SENSE, unlike the imperial system.

Omg I’ve learnt so much from these episodes than I have in the last 5 years! Thanks Donut!! Also the enthusiasm and hilarity is something that makes watching these so fun!
@@m00semanus yes, summing up the "given load" is the same the torque and the "how fast" is the rpm. So [torque x rpm (converted in rad/s)]= Watts, that can easily converted in HP.
Gotta made a small correction: Work is force over distance at an angle (W = Fdsin(theta). As an example, this means that no matter how hard you push a wall with your hands, if it's not moving then no work is being done. Power is work over time so more powerful engines will do more work in the same time. Torque is all good, I would just maybe note that just like with work, the angle of the force matters so the formula is t - Frsin(theta)
I think it's worth noting that torque is a rotational force not a measurement of potential work. Work is Force x Distance, where the distance in the case of a vehicle could be any amount of ground you would like to cover at any given time. Another way to understand the idea of torque is that on a given wheel/shaft, to prevent the engine from moving the shaft/crank, you would have to apply X lbs of force on a 1 foot lever attached to the center of the shaft/crank. A 100 lb/ft engine can move a 3000 lb car easily, but that's just because all it has to overcome is inertia and friction etc. So yes in a way torque is a potential load however in vehicles it is not a direct translation to payload weight and it is not a potential for work because the distance is always subject to change. Horsepower is how fast you can do the work required to get from point A to point B. This is my understanding as of 5 minutes ago, so I could be wrong.
torque is rotational force of crankshaft in engine system based on this video and horsepower is power from the wheel to move the car by a certain amount of time ( workdone per unit time )
@@Handle-i2q that is a very nice and brief summary: "torque is rotational force of crankshaft in engine system based on this video and horsepower is power from the wheel to move the car by a certain amount of time (work done per unit time )"
Got a small hole in the top of a tail light at work once, then it rained. The tail light was full of water in the morning, so I told the guys I needed to drain my blinker fluid. They were all laughing when I told them I was serious. Then I drilled a new hole at the bottom of the blinker, and the water began shooting out. They all lost it.
@@michaeldavis2531 HP is a stupid measurement if you think about it, why would we measure the power of an engine based on a silly calculation about a horse, when we can measure the power based on how much energy it creates/uses etc.
Although I agree he seems reduculess, he fits a RUclips persona. Talking quickly, cutting in and out of frames is far more engaging than someone taking. While I too find it annoying, he's probably getting the younger generations more into physics than your average prefessor
daniel passarelli that's maybe you haven't got into collage and took a bachelor ini mechanical Engineering. This is a basic theory you'll learn in Applied Physics on 2nd or 3rd semester (depends on your campus's curriculum)
@meaturama : While it isn't how we are taught to understand it in school, it isn't totally wrong. Torque = (Force*Distance) while Horsepower = (Force*Distance)/Time. Horsepower is taught as energy/time, or SI units Joules/seconds, where Joules = Force*Distance.
He is wrong though. Force * distance is energy but torque isn't the same kind of force * distance as energy is. Torque is the twisting force and power is the rate of work. Totally different thing.
I really tired and want to understand 100% of this, but most of this is over my head. But, I'm that much closer to understanding. Thanks Donut! Thanks for the funny and educational content.
Incredible. Donut media is one of the best channels on here! Congrats on the hard work and great content guys! I wish physics and math was taught like this when I was a kid.... think it still doesn't, unfortunately!
Great video! A little editing: Work is force over distane... Force (Newtons) X Distance (m) =Nm (joules).... or Force (lb) X Distance (feet) = ft/lbs.... Horsepower is a rate of work over time.... A certain amount of joules of work in a certain amount of time is your power in watts. 746 watts = 1hp
Luke Anthony metric system is based ln real science facts like freezing temperature of water for 0 degree. If Watt had a stronger or a weaker horse the unit would be different
I've watched several explanations, but finally, i understood how and why :) and man, let me tell ya, it ain't easy to explain both torque and HP using comparisons that make sense.
I love those comedy cuts too! :-). Their production value is so on point. Really enjoy Donut content. Yes I'm late to the party, just found Donut recently. Great channel!

I love your technical theory bert .ur the best in Donut channel. Others are wasted.just wasting the RUclips channel . I do also love latest donut channel of the guy repairing cars.
Nice video! Although you made a couple of mistakes in the physics you explained. I'll try to explain as simple as possible the differences between all the units you mention and their physical meaning: lb > this is a pound, a unit of MASS lbf > this is a "pound of force", a unit of FORCE here we remember Newton's law F=m*a, with a in this case being the gravitational acceleration in the earth's surface. These two units are really confusing and in my opinion it is wrong to say "a pound of force" the correct thing to say is "force generated by a pound of mass in the earth" but that's long and i understand why the other term is preferred. Torque > this is a unit of TORSION, which as you explained correctly is a force exerted at a distance of leverage from the point of action. Work > this is a unit of ENERGY and it can be seen as FORCE multiplied by DISTANCE (not time). This makes sense if you see it as the energy you need to apply a force through a distance, clearly you will need more energy to push a car with 100 pounds of force along 10 miles than if you push with the same force along only 10 ft. Horsepower > this is a unit of POWER, which is energy divided by time. If you're not sure you believe me i will show you what in mechanical engineering is called "dimensional analysis". Horse power = ft * lbf / min = [Distance * Force] / Time but remember [Distance*Force] = Energy so we get : Energy/Time. Which, as i mentioned before, is the definition of Power. I hope this helps :D thanks for the video and i'll be happy to check the physics behind any future videos if you ask me to do so!
+Russell Phelan thanks, I get that :) I was responding to +porsche mid 944. The usage of minutes as a time unit in this instance is useful for the later transition from HP as work done by an actual horse to work done by the engine. Adding an extra 1/60 to the equations just makes matters less "readable" on a first glance.
Russell Phelan You made the gorilla physics problem too complicated. The statement "the gorilla WEIGHS 328 lbs" should have told you that his weight was in lbf, not lbm. The calculation is then straightforward, 328(10), as you stated it was supposed to be. Even if the problem had stated "the gorilla has a MASS of 328 lbs", the calculation would be the same, because a 1 lbm is numerically the same as a 1 lbf in standard Earth gravity. It's really not that confusing. If the gorilla stepped on a normal scale, it would indeed say 328 lbs. Why wouldn't it? A couple of points about Imperial vs. SI: It's true that SI is thought out better and more consistent, but calculations are sometimes easier in Imperial units. For example, when calculating fluid pressure at a certain depth, in Imperial units it's simply density*fluid depth. In SI, you have to multiply that by g. Secondly, you may rail against the use of Imperial units, but when I did my senior Mechanical Engineering project, I quickly discovered that all the college emphasis on SI did not match what goes on in the REAL world. I used SI units when I called places to get materials, and I was chided to "speak English!". This was further emphasized when I took the Mechanical Engineering PE exam. The exam VERY heavily emphasizes Imperial units, NOT SI.
Russell Phelan "whatever the acceleration due to gravity is"? Why are you trying to make the gravitational acceleration so mysterious? No one has EVER stood on a scale other than on Earth (did you seriously not assume the gorilla was weighed on Earth?). Therefore, until other planets are colonized, the gravitational acceleration will ALWAYS be Earth gravity, g. Again, you are unnecessarily complicating this. Weight is a force. Scales measure weight. Therefore, the reading is going to be in lbf. Force x distance = energy. You acknowledged that the example said 328*10 is the correct answer. How much does a 1 lbm weigh? On Earth, which is where we ARE, it weighs 1 lbf. Simple. Why do you insist on complicating it? The acceleration is ALREADY "multiplied in".
Horsepower isn’t a measurement of work. It’s a unit a measurement of power, which is work/time, (f*d)/t. 4:09 Horsepower isn’t how quickly force can be produced. That’s (f/t) or pounds per second. Horsepower is how quickly work can be produced, which is (fd/t) or pound-feet per second.
I guess I am the only one. What does 50 hp work for my 1500 pound car? Or 150 hp for 2000 pound car? Which one is the one I will not need to use accelerator?
2:54 actually horsepower is a measurement of power which is equal to energy over time (how much energy you produce at a certain amount of time). Work is a measurement of energy which is equal to force per distance (how much force would you need to move certain object a certain distance). Great video!!

Torque: How much work gets done
Horsepower: The rate of work getting done
or even easier: how much use you make of your strength = Power
Torque: stronk
Torque is power the house power gives torque it’s power. Or else the Torque do nothing without the horse power. You turning the torque wrench is giving it it’s power
So torque is just how long it can keep producing hp and horespower is how quickly it makes the engine function ?
Torque = measure of work done.
Work = Force the engine applies over the length of the crankshaft.
Power = how fast it can do that work.

It's basic physics, not really that hard if you took AP Physics in highschool.
We WERE learning this in High School.
Thing is, we were bored af, we were more interested in that girl 3 seats in front of us, thinking about how to talk to her, and our inteligent but not necessarily smart teacher never thought of connecting this lesson to DRAG RACING, NASCAR, RALLY, RACING.
This channel is great

FINALLY I GOT IT. I watched like 10 Videos on this topic before and now I UNDERSTOOD IT!! Thank you soo much!
This is great man. I never cared for the science behind the numbers, but this genuinely got me interested. And I learnt sum'in!
It's physics! Keep stoking the fire of knowledge-seeking and you will be rewarded! :) You might be interested in further reading at Wolfram, a cool site that allows you to see step-by-step solutions to awesome hypothetical physics problems, it's a lot of fun!

Anodyne Melody I don't understand the video around 6:18. How does 1ft ib x 5252 = 1hp give you the formula to calculate horsepower?
Update. I barely understand it. But I understand it.
Let me teach you something further; if you want to be taken seriously then next time say 'learned something' instead of "learnt sum'in"...
There is a lot of misinformation in this video. He is certainly enthusiastic but he has no idea what he's talking about.
Omg I’ve learnt so much from these episodes than I have in the last 5 years! Thanks Donut!! Also the enthusiasm and hilarity is something that makes watching these so fun!
Pretty much
Torque is how strong it can sipn the wheels
Horsepower is how fast it can spin the wheels
Oh...ok
I disagree mate, hp is torque x rpm ...and other things also
Spin not sipn ( you probably didn’t knowingly type it like that but just saying😀)
“The more ya know”
More correctly, I think:
Torque is how much force come at the wheels.
HP is how fast under a given load.
@@m00semanus yes, summing up the "given load" is the same the torque and the "how fast" is the rpm. So [torque x rpm (converted in rad/s)]= Watts, that can easily converted in HP.
Gotta made a small correction:
Work is force over distance at an angle (W = Fdsin(theta). As an example, this means that no matter how hard you push a wall with your hands, if it's not moving then no work is being done.
Power is work over time so more powerful engines will do more work in the same time.
Torque is all good, I would just maybe note that just like with work, the angle of the force matters so the formula is t - Frsin(theta)
Simplest way I can think about it is, torque is how much work you can do, horsepower is how fast you get it done...
I think it's worth noting that torque is a rotational force not a measurement of potential work. Work is Force x Distance, where the distance in the case of a vehicle could be any amount of ground you would like to cover at any given time. Another way to understand the idea of torque is that on a given wheel/shaft, to prevent the engine from moving the shaft/crank, you would have to apply X lbs of force on a 1 foot lever attached to the center of the shaft/crank. A 100 lb/ft engine can move a 3000 lb car easily, but that's just because all it has to overcome is inertia and friction etc. So yes in a way torque is a potential load however in vehicles it is not a direct translation to payload weight and it is not a potential for work because the distance is always subject to change. Horsepower is how fast you can do the work required to get from point A to point B. This is my understanding as of 5 minutes ago, so I could be wrong.
torque is rotational force of crankshaft in engine system based on this video and horsepower is power from the wheel to move the car by a certain amount of time ( workdone per unit time )
Like as in torque is your threshold?
@@DeepSpaceDubs WHAT ATE YOU TRYING TO SAY!! i is dum... :((
@@Handle-i2q that is a very nice and brief summary:
"torque is rotational force of crankshaft in engine system based on this video and horsepower is power from the wheel to move the car by a certain amount of time

my brain is fried......
Same
that's me.. here as my friend talk about torque and horsepower when I understand nothing about it.. and now my brain is fried
you want a simpler version?
Can i get more torque by adding blinker fluid to my pistons and my crankshaft?
You might want to get some high voltage blinker fluid so it spreads fast over your fuel injector bearings allowing for more horse power and torque.
no, but new muffler bearings will help a lot.
Just slap a new cold air intake from auto zone and you’ll gain 200hp
Got a small hole in the top of a tail light at work once, then it rained. The tail light was full of water in the morning, so I told the guys I needed to drain my blinker fluid. They were all laughing when I told them I was serious. Then I drilled a new hole at the bottom of the blinker, and the water began shooting out. They all lost it.
Piston return springs should also work
Almost done with lot of explanations for torque and Hp videos…. This was the best and last I need to actually understand it !!!! Great job

underrated comment
Although I agree he seems reduculess, he fits a RUclips persona. Talking quickly, cutting in and out of frames is far more engaging than someone taking. While I too find it annoying, he's probably getting the younger generations more into physics than your average prefessor
Didn't get half of what he said.

I learned more here with a simple video than on my school physics program
daniel passarelli dude right? Lol
daniel passarelli that's maybe you haven't got into collage and took a bachelor ini mechanical Engineering. This is a basic theory you'll learn in Applied Physics on 2nd or 3rd semester (depends on your campus's curriculum)
Daffa Abieza yeah I’m in collage but thank god! My career does not have physics.
Markez Singltary I hope it is hahaha
And you learned it wrong, which is why it's so simple. On RUclips, check out a video called: Power & Torque: Acceleration Exposed by AutomationGame
This was and is the best show Donut has and will ever produce.
Everyone makes this explaination to complicated, torgue is the amount of force the motor can produce and hp is the rate at which the torque is made
meaturama How is he wrong?
@meaturama : While it isn't how we are taught to understand it in school, it isn't totally wrong. Torque = (Force*Distance) while Horsepower = (Force*Distance)/Time. Horsepower is taught as energy/time, or SI units Joules/seconds, where Joules = Force*Distance.
So I'm other words, the OP was correct.
meaturama Talk all you want, won't change the fact that you were wrong for saying the OP was incorrect.
He is wrong though. Force * distance is energy but torque isn't the same kind of force * distance as energy is. Torque is the twisting force and power is the rate of work. Totally different thing.
Thank you. As a non car person I still found this really useful. Respect to you.

You're an excellent teacher
Your very last animation has cleared the confusion between horse power and torque !
I really tired and want to understand 100% of this, but most of this is over my head. But, I'm that much closer to understanding. Thanks Donut! Thanks for the funny and educational content.
WE WANT MORE SCIENCE GARAGE!! BART, WHERE DID YOU GO!?!?
Basically
Horsepower is how fast you hit a wall.
Torque is how much of the wall you take with you.
Precisely
no, watch the video
Incredible. Donut media is one of the best channels on here! Congrats on the hard work and great content guys! I wish physics and math was taught like this when I was a kid.... think it still doesn't, unfortunately!
Work is not force per unit time, work is force times displacement.
Meanwhile horsepower is a measure of 'Power' which is work per unit time.
I'm with you :)
Pranita Kakde
Thank you so much, as an engineering major, I was losing my mind thinking, "but Work = Force•distance, so torque is work and HP is actually power
Finally I found the engineers in the comment section!! This guy has no Idea what he's talking about.

What would he use the Turbo for?

Great video! A little editing: Work is force over distane... Force (Newtons) X Distance (m) =Nm (joules).... or Force (lb) X Distance (feet) = ft/lbs.... Horsepower is a rate of work over time.... A certain amount of joules of work in a certain amount of time is your power in watts. 746 watts = 1hp
Those numbers are the reason why we started using the metric system
HP is as complicated as the rest of the imperial system. Guess I start using KW more often now
Manu.MND i was thinking the same thing! KW and Nm are very easy to get used to
Xauntyse Manning in high school physics I learned in Nm and Kw . Pretty simple
Luke Anthony metric system is based ln real science facts like freezing temperature of water for 0 degree. If Watt had a stronger or a weaker horse the unit would be different
Guten Tschüss but if they used kilograms and meters it would have been easier to calculate eg. 10 kilograms lifted 100m in 1 minute

This is the 5th torque video ive watched and by far the best
Mitchell Kelley
I agree ☝️
When I am asked this I explain it like this:
Torque is the amount of work you can do
Horsepower is how quickly you get the work done.
No horsepower is the net of Torque times RPM. RPM is how fast you can get torque ( or work) done

*_Dear God..._*
This...is a bucket.

Nice video! Although you made a couple of mistakes in the physics you explained. I'll try to explain as simple as possible the differences between all the units you mention and their physical meaning:
lb > this is a pound, a unit of MASS
lbf > this is a "pound of force", a unit of FORCE
here we remember Newton's law F=m*a, with a in this case being the gravitational acceleration in the earth's surface. These two units are really confusing and in my opinion it is wrong to say "a pound of force" the correct thing to say is "force generated by a pound of mass in the earth" but that's long and i understand why the other term is preferred.
Torque > this is a unit of TORSION, which as you explained correctly is a force exerted at a distance of leverage from the point of action.
Work > this is a unit of ENERGY and it can be seen as FORCE multiplied by DISTANCE (not time). This makes sense if you see it as the energy you need to apply a force through a distance, clearly you will need more energy to push a car with 100 pounds of force along 10 miles than if you push with the same force along only 10 ft.
Horsepower > this is a unit of POWER, which is energy divided by time.
If you're not sure you believe me i will show you what in mechanical engineering is called "dimensional analysis".
Horse power = ft * lbf / min = [Distance * Force] / Time
but remember [Distance*Force] = Energy
so we get : Energy/Time. Which, as i mentioned before, is the definition of Power.
I hope this helps :D thanks for the video and i'll be happy to check the physics behind any future videos if you ask me to do so!
ever heard of RPM?
+Russell Phelan thanks, I get that :) I was responding to +porsche mid 944. The usage of minutes as a time unit in this instance is useful for the later transition from HP as work done by an actual horse to work done by the engine. Adding an extra 1/60 to the equations just makes matters less "readable" on a first glance.
Russell Phelan You made the gorilla physics problem too complicated. The statement "the gorilla WEIGHS 328 lbs" should have told you that his weight was in lbf, not lbm. The calculation is then straightforward, 328(10), as you stated it was supposed to be. Even if the problem had stated "the gorilla has a MASS of 328 lbs", the calculation would be the same, because a 1 lbm is numerically the same as a 1 lbf in standard Earth gravity. It's really not that confusing. If the gorilla stepped on a normal scale, it would indeed say 328 lbs. Why wouldn't it? A couple of points about Imperial vs. SI: It's true that SI is thought out better and more consistent, but calculations are sometimes easier in Imperial units. For example, when calculating fluid pressure at a certain depth, in Imperial units it's simply density*fluid depth. In SI, you have to multiply that by g. Secondly, you may rail against the use of Imperial units, but when I did my senior Mechanical Engineering project, I quickly discovered that all the college emphasis on SI did not match what goes on in the REAL world. I used SI units when I called places to get materials, and I was chided to "speak English!". This was further emphasized when I took the Mechanical Engineering PE exam. The exam VERY heavily emphasizes Imperial units, NOT SI.
Russell Phelan "whatever the acceleration due to gravity is"? Why are you trying to make the gravitational acceleration so mysterious? No one has EVER stood on a scale other than on Earth (did you seriously not assume the gorilla was weighed on Earth?). Therefore, until other planets are colonized, the gravitational acceleration will ALWAYS be Earth gravity, g. Again, you are unnecessarily complicating this. Weight is a force. Scales measure weight. Therefore, the reading is going to be in lbf. Force x distance = energy. You acknowledged that the example said 328*10 is the correct answer. How much does a 1 lbm weigh? On Earth, which is where we ARE, it weighs 1 lbf. Simple. Why do you insist on complicating it? The acceleration is ALREADY "multiplied in".
Russell Phelan No one is going to mix SI and Imperial numerical values, unless he's not paying attention to keeping his units straight.
Math and physics teacher here! Amazing video! I'm going to show my students!
Horsepower isn’t a measurement of work. It’s a unit a measurement of power, which is work/time, (f*d)/t.
4:09
Horsepower isn’t how quickly force can be produced. That’s (f/t) or pounds per second.
Horsepower is how quickly work can be produced, which is (fd/t) or pound-feet per second.
I noticed this too haha
I was just about to say this
Otherwise, it would be called Horsework, instead of HorsePOWER.

2:54 actually horsepower is a measurement of power which is equal to energy over time (how much energy you produce at a certain amount of time). Work is a measurement of energy which is equal to force per distance (how much force would you need to move certain object a certain distance). Great video!!

All I got from this video was how a wrench looks like
suavè I know right? I was lost when they mention pi in the video.
They had to use Pi to calculate the circumference of the wheel (and therefore, displacement)
Force= mass x acceleration
Torque= length of lever arm x force
work= force x displacement
Power = work/time
Best series of donut media till date .
Torque :- how much work is done
Horse Power:- rate of work done
Heart muscle = horsepower
Biceps, triceps, pecs = torque
