Physics on Khan Academy: Physics is the study of the basic principles that govern the physical world around us. We'll start by looking at motion itself. Then, we'll learn about forces, momentum, energy, and other concepts in lots of different physical situations. To get the most out of physics, you'll need a solid understanding of algebra and a basic understanding of trigonometry.
About Khan Academy: Khan Academy offers practice exercises, instructional videos, and a personalized learning dashboard that empower learners to study at their own pace in and outside of the classroom. We tackle math, science, computer programming, history, art history, economics, and more. Our math missions guide learners from kindergarten to calculus using state-of-the-art, adaptive technology that identifies strengths and learning gaps. We've also partnered with institutions like NASA, The Museum of Modern Art, The California Academy of Sciences, and MIT to offer specialized content.

"Jimpulse" I love it.. thank you
second physics 1 exam in 90 minuites and here I am.
Very good summary towards the end
"Jimpulse" Nice catch bro
Well explained and simplified thankyou sir
Where can you do this demostration of impulse?
I want a video of my self too
Hi sir, I’m a bit unsure on when to use a negative/positive sign when calculating the net impulse ?(like when you said that it should be -10m/s instead of just 10m/s)
youll have to use your brain in that one
Basically you cave to assign a direction to a sign. Its usually so that right means positive and left means negative.
Awesome.
Very helpful 😊
Great video!
sir ! if we take impulse for force acting by by ball on the face for the same time then will be the direction of force and impulse in that case ?? answer plz
Hi Afnan! I am a little unsure about your question. The direction of impulse from face on the ball and force will be the same. I hope that is what you are asking
He explains this nicely in the summary towards the end
Thank you ! = ]
Why does Jape Fat sound like a rude thing to call someone to me?
Gud vid (hot voice tho) XD
i love doggos ouch :*
Heyy u remember me ??
Hello,
I badly need help in solving these problem. These are part of my review and I can't really solve it. Hahaha. P.S. I am having a hard time understanding this. 😅
I hope that you could give me a solution and that would be a big help for my review. Thank you so much!
1. A 9ft ball moving at 10 ft/s collides head on with a stationary 1lb ball. Determine the velocity of each other after impact if (a) they stick together, (b) thr collision is perfectly elastic, and (c) the coefficient of restitution is 0.90.
2. A 2kg block of wood rests on a tabletop. A 7kg bullet is shot straight up through a hole in the table beneath the block. The bullet lodges in thr block and the block flies 25cm above the tabletop. How fast was the bullet going initially?
I was playing hand ball in gym class once. A boy hit it, it flew into the air, and bounced off my face. Luckily my glasses weren’t broken and I kept wiping my nose to make sure it wasn’t bleeding
what i wanna do in this video. what i wanna do in this.... v-i-d-e-o....this v i i i i d e e e o o o o. Where is Sal?
