I HAVE A TEST in 2 days on these concepts. Thank you so much for always being there, you are truly an underrated educator. You have carried me through 6+ years of math, including AP Statistics, AP Calculus AB(as of now), AP Physics, and Chemistry. I honestly am glad that there are people like you to make online school so much easier.
bro i love you your the fking god my main exams are coming soon and from your help now I'm pretty sure ill get a good grade in my exams i really wanted you to help with maybe joining your patreon or such but I'm just student and i don't earn any money so for that reason i couldn't join your patrion to support you I'm really sorry about that but remember bro i love you soo much you helped me a lot i will always remember you. bro your physics explanation are in next level the topics i didn't get it for years i understood them by watching your videos thank you sooo much ❤❤❤❤❤❤❤❤❤❤
abang you really helped me through final. i had chem final yesterday and i watched your videos, most of it showed at the exam 😭😭😭 you really helped me, thank you. i hope you always have a great day
Oh my god. Actually a friend of mine recommended your channel but I didn't make the time to watch just until now. But really, I never knew the topic that I was weakest at would become my strongest topic in what, 29mins 29 secs god....the thing I spent days contemplating on got solve within less than half an hour.....
x and delta x have been used interchangeably in the video, which makes it confusing. If x is assumed to be the distance between ends of spring, then F=-k*(delta x), W=-1/2 k*(delta x)^2.
Yes very confusing part because x is usually the strain caused by the stress so how they can be used interchangeably. If x is total length then using ∆x makes sense
for 4th question just do fp=kx then w/2 = fs where f=fp and s = x so fp= kx == 250x0.75 == 187.5 187.5 x 0.75 = 140.625 / 2 therefore work required = 70.3125 J or 70.3 J
I have one small question: Why doesn't work done equal to the negative change of potential energy, which is represented by W=-deltaPE. I remembered that this is what my teacher taught me.
I always fail to understand why you are so good when ever am watching your videos.i have a question, why is a spring balance used to measure weight but not mass?
soo funny thing ... i dont actually need this for school. it feels strange to come back to the physics we learned at school because we have found a practical use for them ! normally as a kid youre like "this is useless i am never using this in real life !" but now its completely differant . i genuenly need this for something ! . i am currently programming a car physics system for a video game and cars have springs for their wheels. in order to simulate car springs i need to know exactly how those physics work and implement the math into my programming. i wish school was able to teach us about practical uses of math and physics like this more often. that way we at least care about what we are learning because we know what we want to use it for . but no its always vague and abstract boring concepts that we dont know how to use.
It has nothing to do with acceleration, there are numerous ways to calculate the force exerted that don’t include acceleration. If work is equal to force times distance, then the force is equal to the work applied divided by the distance.
I'm a bit confused abt the last part involving the Work done by the restoring force, I mean initially when the applied force is stretching or compressing the spring to a certain, I have the belief that only the applied force is stretching the spring, not the restoring force, I hqve the believe the restoring only acts when the spring is returning to its natural position , and then the displacement (opposite to the stretched displacement) and the restoring force are in the same direction, so I'm confused how it's work done by the restoring force is negative, to me it feels its should be +ve.
Elastic Potential Energy (PE) = 0.5kx^2. The unit will be N/m • m^2 = Nm = joules. Energy is measured in joules. Note: 1 joule = 1Nm. However, the restoring force, F is measured in N.
How does the gravitational wave emitting from a planet differ from a rubbee band being stretched out maybe the gravitational field is stretching out some other force than elastic energy stretches out any ideas to prove or disprove this? I need all possible awnsers please no insults those are a waste of time im trying to learn and grow not hear little 2 year olds throw insults
At minute 22:58 why is ΔX² = (Xբ² - Xᵢ²). I don't really understand the logic behind it, it seems more plausible for it to be (Xբ - Xᵢ)². Can someone please explain?

A constant. Force increases linearly with length (more force is required to pull further) and the factor by which it increases is called k. So it's just the relationship between F and x.

Such an awesome teacher! You are so much better than a textbook lol
Thanks man. You're seriously a life saver. I'm in middle school right now and I wished I'd found you sooner. Better late than never, this is great....

Provided the elastic limit is not exceeded, the extension in an elastic material is directly proportional to the load or applied force. (Hooke's law)
I love your style of teaching because you give us everything ie the principles behind every law and it's applications
You are the best.
I've question though , is physics always easy like this?
not really, whenever you get to nuclear physics and quantum mechanics it becomes pretty difficult for most people
I see this video 8 hours before my exam I feel relief you are the best thank you very much ❤❤❤❤love you 😍 💋 😘
I’m about to put on an academic performance like never seen before
You are god sent. I mean how is it possible to understand a whole chapter in less than 30 min.big ups bro.

Good job.. he's really calm and understanding...how I wish we had such lectures
Keep up the amazing work sir!!
I have tomorrow the year's end exams and I have this lesson but whatever I have done I couldn't understand it but now it feels easy, good job man
I had an emergency assignment to be submitted this morning, you literally saved my ass bro 💪🏼
can the same theory be applied if we press the spring ?? How ever as everyone else say you are truly a life saver

This is so amazing bro
Thank you very much for your clear explanations
I love how he says length. “Lenf”
Nice video! I love you!
Thanks so much, am having exams on strength of material tomorrow
17:57 dont we define the change in X as Xf - Xi ? when we make (Xf - Xi)^2 , doesnt it have to become Xf^2 +Xi^2 -2Xf.Xi ?
Thanks😊
But it would be better if you had given an example of spring being compressed vertically😊
Physics for this man like playing game 👏👏👍
Thank you very much. I've been finding out why (-) has been included in this fooking Eq...
Thank you brother ❤❤
Me not understanding any single thing this dude is saying but enjoying his voice and learning: *I like your funny words magic man*
YOU SAVED ME!😭😭😭😭💕💕
Amazing works 💯.
for 4th question just do fp=kx
then w/2 = fs where f=fp and s = x
so fp= kx == 250x0.75 == 187.5
187.5 x 0.75 = 140.625 / 2
therefore work required = 70.3125 J or 70.3 J
Great explanation Sir!
Just got our "specific topics" for Wednesdays exam. You got the first 2 out of 8 so far lol
Thank you
omg this was very helpful thank u sooo much

Same boat bro, I'm currently studying engineering in game design, and a lot of physics is involved in games
at 16:17 I can't understand how when the acceleration is 0, the work done is equal to the potential energy change, can someone please explain ?
It has nothing to do with acceleration, there are numerous ways to calculate the force exerted that don’t include acceleration. If work is equal to force times distance, then the force is equal to the work applied divided by the distance.
@@yuvalkoren4070 Thankyou !
Me after seeing this video again after years:
"Why haven't I subscribed to this guy yet?!"
There is a mistake on question 6; you multiplied 1/2k by the difference of the squares of x rather than by the square of the difference of x.
Cheers
Elastic Potential... pretty cool 🙂
nice vedio i have been watching since i was in grade 6 and i am in nineth grade

This is excellent, thank you 😊
Thanks buddy much importatnt
How will you find x if the only present is the mass?
If k is a constant how it's value can change from spring to spring
Springs in parallel and series plz
So for problem nr 7 (which we see a glimpse of it at the end) i got:
a) 490 N/m;
b) 6.272 J;
c) -12.544 J;
d) 40 cm.
How far was i?
c should be 11.392 i think because we use the formula Ug=mgh
how did u solve d?
i hope u still remmber after 5 months
@@sarahnaji7563 lol
U saved my ass again.
16:51 doesn't work equals the change in kinetic energy and not the potential energy ?
So it would be
W = PE = 1/2 F x
On #4 can someone explain why we multiply it by 0.5 and what does the triangle have to do with out problem in the first place?
The 0.5 is just the ½ in decimal. It makes it easier to multiply and we need the triangle because the force is varying.
at 16:15 why isnt the force negative? isnt it 1/2-KX^2?
Elastic Potential Energy (PE) = 0.5kx^2. The unit will be N/m • m^2 = Nm = joules. Energy is measured in joules. Note: 1 joule = 1Nm.
However, the restoring force, F is measured in N.
its not in the same direction with force thats why it is positive
How does the gravitational wave emitting from a planet differ from a rubbee band being stretched out maybe the gravitational field is stretching out some other force than elastic energy stretches out any ideas to prove or disprove this? I need all possible awnsers please no insults those are a waste of time im trying to learn and grow not hear little 2 year olds throw insults
Question 6 is incorrect 45cm is 0.45m not 0.045m. Therefore the answer is -14.6832J
4.5 cm, not 45.
At minute 22:58 why is ΔX² = (Xբ² - Xᵢ²). I don't really understand the logic behind it, it seems more plausible for it to be (Xբ - Xᵢ)². Can someone please explain?
Delta X squared means X^2 - X^2
(Delta X)^2 means (X^2 - X^2)
So the difference is the parentheses
for question's 1 and 2, why is the formula: F=kx? Shouldn't it be this: F=-kx, that's what my textbook is telling me?
To stretch a spring it’s positive and to compress it, it’s negative
16:52 what if acceleration is not 0,
I wonder if f net is always 0 in this law?
if the acceleration is not 0, does the total work equal KE + PE?
if it is equal how do we find KE?
How do you expand Deltax^2 as x_f^2-x_i^2? You are missing a term, aren't you?
Isn't work = - change in potential energy?
nvm he explains that in the end of the video lol
23:29
How can I be your member
Every time he says hookes law I hear it as cole slaw
