i've literally been trying to understand this the whole day.. i watched soo many videos but this is the one that really explained it in a way i can grasp... thank you so much
Yo I had to come here and relearn this part of physics to settle an argument. Ahaha. If you were wondering, the argument was whether a pistol slide (that uses a spring) exherts the same amount of force from full compression as opposed to when it is partially locked. It sounds dumb but a manufacturer of a very very very expensive 1911 is trying to say that dropping the slide into battery while it is empty is bad for the components and the other side is laughing at them because a weapon is designed to take 20k+ psi of force when firing a round. My argument was that a spring's force is a factor of how much energy is used to compress it fully vs where it is when compressed partially. The argument is wild. It's actually turned into a biiiiiiig debate in the RU-vid gun community. If you were to chime in with the math you could settle the debate once and for all and maybe get you some traffic lolol. 😂😂😂
I do not have other videos on another channel unfortunately. I am working on E&M content currently however! Probably won't have any new videos until next year, sorry!
@@HowToPhysics all good. I suppose I won’t need it anymore but I’ll make sure to recommend it to my friends who will. Thanks for all the help on mechanics!
if the acceleration is not constant, how we assumed that acceleration is constant? if we think like acceleration is varies by time what will change? thkns for video
Your teaching style is very helpful, it makes these topics seem less complicated. Thanks! Also: Why does the point mass have initial angular momentum in the second problem but not the first one? Is it because it started with a velocity?
Thank you! And yes, you can think of it as linear momentum turning into angular momentum too if that helps. I agree that it's a little weird to say that an object moving in a straight line has angular velocity :)
Awesome video, just would like you to confirm if you are gay because my gaydar siren was blaring when you described the features of the car and my new dog. Thank you for the video!
Hello, why does the law, linear quantity = angular quantity x r not apply for toruqe as then it would be F=TorquexR when it is really Torque=ForcexR? Thank you
Thank you thank you so much. I'm in a testing company and for so many years I was the grunt. This video course has helped me learn more about vectors using the calculator.
This video is for my AP Physics students and g=10 for problems on AP tests. It's a simplification that makes solving most problems a lot faster and your answer is generally very close to what you would get with 9.8 or 9.81. Hope this helps!
Honestly the Princeton Review books are very helpful I think. They make a new one every year and are about $20 www.princetonreview.com/college-advice/ap-physics-c-exam ... They're not perfect and the questions won't be worded in the same way as actual AP test questions but the content review is very straightforward and helpful!
Hi, I noticed you didn't bring over the T after cancelling out the VoT (right before equaling everything to zero) was this in error? If intentional, can you explain the reasoning behind it? really enjoy your videos btw, you explain everything so much more clearly than my professor >_<
It does not! The only time the angle of the ramp would matter is a special case where the ball is sliding or slipping while rolling but that is an unlikely physics question.
So i tried it a slight different way. One that i find easier I first Max Heigh Ball reaches using -- H= V^2 Sin^2(THETA) / 2g After i got my Max Height of 7.15769 meters I then used that to find TIME. t= sqrt(2(H + h) / g with this i got time of 1.2086 seconds After i used this formula to find RANGE R= Vx t Vx being V* Cos 37 My final answer was 14.4 m with roundings Im still learning physics! But i just figured it out this way and thought it was easier for me thank you
This is a totally acceptable way to solve the problem! When using sin and cos, error will propagate if you round the decimals so being off by 2m sounds reasonable.
