AP Physics 1 review of Momentum and Impulse | Physics | Khan Academy

In this video David quickly reviews the momentum and impulse topics on the AP Physics 1 exam and solves an example problem for each concept. Created by David SantoPietro.

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.

At 5:40, you solved for momentum, but it asks to solve for velocity. -40kg*m/s needs to be divided by the 2kg that the rocket weighs. that'll give you the answer -20m/s.

I wish you all good luck guys! Im just aiming for a 4

At 10:12 your answer choices should be vx and vy, instead you only have vx values. But great video overall, thank you!

For the Elastic and Inelastic problems, the explanation makes sense but the calculations indicate that kinetic energy is conserved. I'm confused. Based on my calculations, KE = 2MV^2 before and after collision.
