Someone as lazy as me cannot spend more than 5 minutes learning about something and you said it with such simple grammar that I can actually understand unlike another other videos thanks
It’s amazing how I spent a whole 90 minute lecture trying to figure out which was which and then just watching a short video and understanding everything.
motion : change in position wrt time speed : distance / time velocity : speed w/direction acceleration: change in speed and/or direction ( sounds like speeding up , but incl slowing down as well 👻
Can you explain this problem? ---Elizabeth rode her bike down the hill. At the top, she was riding at a speed of 10 miles per hour. At the bottom, she was going at a speed of 15 miles per hour. It took her two-tenths (.20) of an hour. What was her acceleration? Thanks!
So, acceleration is change on velocity over time. We subtract our final velocity (15 mph) from our initial velocity (10 mph) and divide the result by our time in hours (0.2). This will give us the acceleration in mph squared.
i commented on another video of yours and this video was equily as helpful! Thank you! (btw i agree with the comment that said you have a nice mustache)
speed - the rate at which an object changes position = distance/time instantaneous speed - the speed of something in that instant: shows on car speed gauge average speed - the average speed of an object calculated after its reached its destination velocity - speed with direction (74m/h east) acceleration - rate at which velocity changes = distance/time^2. changing velocity = acceleration. doesn’t have to speed up
You'd think that would be true but no apparently, if your in a college physics class that explanation would make you miss questions on an exam because velocity isn't as simple as that. Velocity = displacement/time , NOT distance. Distance is the measurement of how far something has travelled, Displacement is when an object moves from one point to another and does not care what comes in between. To fact check this for a problem like Joe travelled 10m east then doubled back 2m west to reach his house calculate velocity/speed. For speed the equation would be speed= 12m/time , and for velocity it would be velocity=8m/time. 12m and 8m are not the same. Because displacement does not care that you travelled 10m east then 2m west, it only cares that you got to 8m from your starting point. This is what I was told and I keep seeing videos contradict this. Idk if im wrong or what.
Idk if im just wrong b/c im in college and when it comes to velocity its more complicated than just speed with direction. In my class they say its specifically displacement over time and displacement isnt the same as distance. Distance is the measurement how far something has traveled while displacement is when an object moves from one location to another. So you travel 10 m east then double back 2 m west , in terms of distance it would be 12 m but for displacement it would be 8m. That is what I am being taught and I feel confused because when you go to input that into equations they are different. Speed = distance/time , Velocity = displacement/time. With the case of 10m east then 2m west that would effect the overall averages and definitely would not be just distance/ time + direction for velocity. Because if that would be the case it would just be 12m east like you said which isnt true, or for my case +/- denote a direction on an axis and it would be a total velocity of 12m which would be to the right on the x-axis 12m, but in actuality it is 10m right then 2m left which gives you a displacement of 8m which effects the equations and instead of 12m/h for the total trip it would be 8m/h? Idk that is along the lines of what im being taught and it gets confusing.
Hi Virgil, Could you please help me calculate the speed and force of a moving vehicle that run into my vehicle that was stationary. Both vehicles waight 1500kg. The moving vehicle travelled 160 metres before collision. They managed to push my vehicle by 3.5 metres. Could you please help me work out the speed of the moving vehicle and the force of impact ? Many thanks Helena
I got a motorized bike I heard if i put a small rear sprocket it will go faster but for hills it will be harder its like more top speed but less acceleration? Any explanations? Or help?
It takes a lot more work (Joules) to move something up rather than just straight ahead. The small motor needs more power (joules/second) to be effective going uphill.
Velocity is speed with a direction, and speed is distance/time. So you divide your distance (2400 m) by your time (9.6 minutes) and add a direction (east, up, to the left, or something given in the problem), and then you have velocity. Make sure the answer is looking for meters/minute though and not meters/second or something else.
Ok, how do I calculate my G's in an accident if I'm going 35 mph and come to a quick stop? I swerve not to under ride a truck. I now have a brain injury.. trying to figure out G's need to cause a brain injury.
This was better than the 1 hour explanation In my classroom thank you!!!
Sometimes less is more.
14 hour*
ik right
i stop paying attention after 1min of my teacher talking :P
@@2MC u r right
this 2 minute vid has explained more than a whole month of physics, thanks
(btw nice moustache)
You're so welcome!!
And thanks for the compliment 🥰
Agree
2 semesters with physics, and i couldnt find yet a teacher like you.
I'm sorry you have had such bad luck, but I'm glad you found my channel and that it helped.
Same
Teachers who make physics class boring are criminals ~ Prof.Walter Lewin
Same
So.......
1) rate of change of distance=speed
2)rate of changecof speed=velocity
3)rate of change of velocity=acceleration
Yes! Excellent summation!
Saima Gillani
2. The rate of change of speed in respect to a direction since its a vector quantity
Nice
@@ngwemildred7847 Exactly what I was thinking. I'm surprised the 2 minute teacher didn't catch it.
Rate of change speed with direction is not velocity......final change in distance with direction is velocity
Someone as lazy as me cannot spend more than 5 minutes learning about something and you said it with such simple grammar that I can actually understand unlike another other videos thanks
Glad I could help.
i love how you explained 3 lessons in 2 minutes rather than needing 3 50 minute sessions thank you so much for this
It’s amazing how I spent a whole 90 minute lecture trying to figure out which was which and then just watching a short video and understanding everything.
That's what I'm here for 😊
Thanks for making it easier, I can't believe I understand it in two minutes more than I understand it in the classroom
I clicked on this video just because of his mustache and then I found the best explanation of this topic ever
Thanks 😊
For just 2 minutes, this video taught me way more than a whole class period. Thanks!
(also nice mustache dude)
My wife always thinks I’m looking at girls late at night but I’m learning the difference between speed, velocity and acceleration.
😭😭😭
😂
😂😂😂
This is much better, simpler. Thanks
Thank you so much. What make you start this channel?
I love 2 Minute Classroom!
Thanks Scotty, 2 Minute Classroom thinks you're pretty okay too!
its actually really effective teaching, better than my teacher
**i hope she doesn't see this XD XD**
Marie Magdy XD XD XDX D
my teacher couldn't make me understand this in a week, you just did it in 2 minutes!! thankyou so much :)
You're welcome 😊
THANK YOU!!!! These basics go overlooked too often
I couldn't agree more. You're welcome!
Science was so confusing for me before, and two hour semesters arent any help, but this short video increased my grades by 10% :D
crash course is usually good but physics is rubbish. 2 minute classroom u are an absolute legend
Thank you my friend.
Hello
Really appreciating all doubts are cleared. Thank you, sir!
Glad I could help.
I am in 11th grade science student who still don't know the difference
Came here to clarify a day before the exam.😢😊😊
No shame in not knowing the difference. Glad I could help clarify things.
Way better than the hours ive spent studying with textbooks. Thank you
Sorry you spent so long studying without much to show for it. But I'm glad you found my video and that it was helpful for you!
thanks, have a test soon wish me luck
You don't need luck, you'll crush it with pure skill!
@Addison Presnell Good call out! I actually meant "pure" and just edited it.
Thanks wish me luck for my exam tomorrow!
Good luck (3 days late 😭)
I hope it went well.
@@2MC thanks! The teacher wasn't here so we are having it this Thursday
Chelly Reverse what did u get
Jyoti Jyoti howd it go
motion : change in position wrt time
speed : distance / time
velocity : speed w/direction
acceleration: change in speed and/or direction ( sounds like speeding up , but incl slowing down as well 👻
Damn this video is so short yet so educational this channel is super underrated
I still don’t understand what does acceleration mean? Would you please explain
Acceleration is a change in velocity. Velocity is speed with direction, so any change in speed or direction will create acceleration.
2 Minute Classroom thank you so much that’s a very good explaintion
The text books just make it hard and hours of understanding but you make it easy to learn in two minutes
Thank you! I'm just trying to do my part.
Saying thanks from 6 years in the future!
Wow! Thank YOU!
i can’t thank you enough, i crushed the exam. you’re my flipping hero.
Change speed due to direction,call it velocity change velocity,call it acceleration,CHANGE THAT TOOOO DO TORTURE ALL DAYYYY
👍
Many Times.....Less Time Helps Us To Grasp More..........RESPECT From INDIA.....
Thank you my friend.
Velocity =displacement /time?
yes
Yep

So, acceleration is change on velocity over time. We subtract our final velocity (15 mph) from our initial velocity (10 mph) and divide the result by our time in hours (0.2). This will give us the acceleration in mph squared.
My teacher hates me because I don’t understand well but this video made me understand thx!
I have a science exam tomorrow first thing in the morning, might pass because of this video!
4 years ago but still helps! Thanks!
better than my teachers 2 hour explanation 🐐
Thanks for breaking these concepts down in a bite-sized 2 mins
I can't explain how helpful this video is. Thank you sir
You are most welcome
THANK YOU. So many RUclips videos explained velocity as speed
i commented on another video of yours and this video was equily as helpful! Thank you! (btw i agree with the comment that said you have a nice mustache)
Best explanation I have seen
Glad you think so!
This is so much better than the other video my science teacher sent us
I'm glad to hear that it helped!
Thank you. our exams will be tonmorow ! thanks for your wonderful explanation
I hope it went well.
2 Minute Classroom Well It’s Done
All you said Is included on the exam Thanks!

speed - the rate at which an object changes position = distance/time
instantaneous speed - the speed of something in that instant: shows on car speed gauge
average speed - the average speed of an object calculated after its reached its destination
velocity - speed with direction (74m/h east)

Keep it up
Thank you! Will do!
All my concepts about speed acceleration and velocity got clear here
Glad to hear it!
I'd been trying to understand what acceleration is for some time. With your quick guide, I could understand it within minutes.Thank You! 😊
How can the velocity of an object change when its speed or direction changes?
Because velocity is basically speed with direction, so if you change either, you change the velocity.
@@2MC thanks you helped me with my science homework 📄
This is the first I’ve ever heard of you, but I know I like you already. I hope my teacher keeps using your vids!
Thank you my friend. And I hope so too.
😁😁😁
is velocity displacement over time?

Thanks for the easy explaination sir!
Is velocity written in m/s squared?
No. Those are the units for acceleration. velocity would just be m/s with a direction.
man i have been taking this lesson for 15 classes and I did not understand then I found this video and now I am an expert
yo i spend one hour in my class room and you taught me every thing in two minutes i will see you on my new ps5 im about to get
in my school my teacher explained for like 4 lesson and it just flew out of my mind your 2 minute video is much better😁😁
Glad it helped!
didnt expect you to reply to such an old video
So what about an equation , like you have the force but not the acceleration and you also have the mass ? How would you solve it?
Wonderfully explained.
Than you!

love the mustache bro, keep the videos up my guyyyyyyyyyy i subbed and liked and also did other stuff
Thank you my friend
Powerful video. Congrats!
Thank you 🤝
No critics, well explained in the simplest of terms 👍👍👍👍👍
but velocity= displacement/time so we will calculate speed of displacement na ?
Great point.
Really it's better than 3 period in school of studying the same topic
Glad it helped.
this cleared all my concepts in such a short time thanks a lot
Glad it helped.
Thanks man I’m in 8th grade and this helped me alot
Glad to hear it!
Why acceleration has t^2? Its definition is a change in velocity over time, then why not just t rather than t^2?
Because velocity is distance over time, so it already has a unit of time. So when we bring in another "per time", we get time squared.
@@2MC oh man thanks. A to the point two second reply :)

It takes a lot more work (Joules) to move something up rather than just straight ahead. The small motor needs more power (joules/second) to be effective going uphill.
The best explanation but also the quickest
Best of both worlds.
Yup
this was an awesome breakdown thank you so much
you are welcome.
How does the unit of acc.be m per sec.?
🤔 I don't understand your question...
The unit of acceleration is m/s*s i.e., m/s2
But if a velocity have two numbers like 2,400 meters and 9.6 minute how can i solve that problem
Velocity is speed with a direction, and speed is distance/time. So you divide your distance (2400 m) by your time (9.6 minutes) and add a direction (east, up, to the left, or something given in the problem), and then you have velocity.
Make sure the answer is looking for meters/minute though and not meters/second or something else.
@@2MC ok thank you know I understand
Here I am at 50. All my life I thought I couldn't understand this thing. Thank you Sir
Much better explanation than what I paid for an hour lecture.
Not only science is cool you are also an excellent teacher
Thank you my friend
@@2MC you welcome my dear teacher
Omg I love 2mins classroom
Thnk you very much sir ♥️
I was wondering, if i throw a ball vertically up in the air, would acceleration at the highest point equal 0?
Yes. At that point it is not changing velocity therefore it's acceleration is zero.
You helped me to understand in a very short period of time .
Thank u
You are most welcome
جزاك الله خيرا ،
هداك الله إلى الصراط المستقيم🖤
Better than my teachers 1 hour lesson not gonna lie
thank you! I just spent 15 min watching videos trying to understand velocity, and now I do from your simple video explanation. thank you, sir!
i love 2 minute class better than 1 hr class
Absolutely 👍
So do acceleration has direction as well?
Thanks sir! That was an amazing explantion in less time!😃
this is way better than teaching
Well, technically it is still teaching.
This is very helpful for my upcoming test Thank you!!
Best of luck!
great video, the last line, "Science is so fun" spoken like a true sheldon.
So Truuueeeeeeeeeeeeeeee
Thank u so much sir 🤧🤧 class 9 doubts are completing now in class 11 😭😭
This was a very interesting video. I have understood it so well and also learnt something about acceleration, speed and also velocity. Thank you
But surly you need the starting speed and the end speed to figure out the acceleration?
It was so easy to understand and so fast!!!
Excellent 👍
Hello, why is acceleration distance/time^2? And could you please give an example of how to calculate the acceleration?
Ok, how do I calculate my G's in an accident if I'm going 35 mph and come to a quick stop? I swerve not to under ride a truck. I now have a brain injury.. trying to figure out G's need to cause a brain injury.
Is it possible to keep speed constant while changing direction?
Because at the nexus point speed would have to change right? So it’s impossible to change acceleration through direction without changing speed?
Sir I have a question about it can I ask?
Go ahead.
