AP Physics 1 review of 2D motion and vectors | Physics | Khan Academy

In this video David quickly explains each 2D motion concept and does a quick example problem for each concept. Keep an eye on the scroll to the right to see where you are in the review. 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.

wow, explain all of this in 13 minutes somehow I understand the topic.
My teacher here talking for a whole 45 minutes and I was like WTF are you saying

[samweiss]

Is there a review sheet like the one for the 1D motion?

Can you please make a video on circular motion at constant speed

[TheKiyoshiRyu]

Hey guys, I had a question. Let's say that the left is the negative direction and an object were to be going to the left at a constant 5m/s. Would the object's velocity be -5m/s to the left or would it just be 5m/s to the left?
