COLLISIONS! A big part of physics is understanding collisions and how they’re not all the same. Mass, momentum, and many other things dictate how collisions can be unique. In this episode of Crash Course Physics, Shini sits down to lead us through an understanding of collisions. Plus, she brings a long our old friend Sir Isaac Newton.

Unique content! I found no better.
is this the same as momentum

She speaks so flawlessly!! And clearly !!! She can simplify even the hardest of the topics !!!
Excuse me Mr. (or Miss) Video Editor, your job is to edit out every time she takes a breath.
Finally! A video I found an actual use for making legitimate use for YouTube's slow-down feature rather than only making people sound drunk. ?
I kind of understand this I’m not even in grade 7 lol
What's her name?
how is it that i can have a teacher tell me something for an entire semester but won't understand it until i watch a 10 minute crash course video? i'm killing this physics final today!
The ball equation on when the ball hits the wall and changes its force in half a second. The equation itself was correct but the answer is 3.125. This is important for people taking the AP Physics C test, for they need you to round to the nearest 3 decimals.
3:18 That isn't quite true.
"For this to be a true elastic collision all of the kinetic energy from the white ball would have to be transferred to the red ball."
For the collision to be elastic, the white ball doesn't necessarily have to transfer all it's kinetic energy to the red and come to a complete stop. The white ball can absolutely still have kinetic energy after the collision so long as the total energy of the system (the sum of the kinetic energies in each ball) is equal to the kinetic energy of the white ball before the collision. True, if the white ball transfers all of it's kinetic energy to the red, the collision is elastic. However, this does not have to be the case for ALL elastic collisions in this scenario.
me: im going to read my barron's book for physics
me instead: watches physics crash course while debating making brownies
update: i made the brownies and will be giving them to my classmates tomorrow
Technically, cue balls weigh a half an ounce more than the rest of the billiard balls so in order to stop a cue ball in its tracks, other forces would have to come into play. It's pretty good practice to hit a cue just below center to create a backspin which adds a little more friction to the equation, preventing the cue ball from following the 8-ball in causing you to lose that game where you ran the table on Mick. You won on technicality Mick! I'm still better than you!
So technically Aristotle wasn't wrong just that he didn't have calculus
You need to already know the coursework to understand this
her hair so shiny
May the F=ma be with you young jedi
up to the par
I have a question, if you have two objects and they collide. Why is all the momentum transferred to the other
Who is she?
In Highschool, Kenya, we call it the Centre of Gravity, not mass. Not much of a difference, but it shows how different our curriculum is.
It bothers me to hear a British lady use the word "math", rather than "maths".
