I was overviewing AP Physics 1 when I saw that a lot of lessons seem incomplete. The first two alone seem out of order, with the second lesson deriving and explaining the kinematics equation but the first one's practice problems use it.

But you also know the power output of the car to be 130000W. So using the power formula again we can discover the velocity of the car on the incline. v = P/F = 130000W/4318N = 30.1m/s. So the maximum speed of the car on the incline is 30.1m/s. AP®︎/College Physics 1 5 units · 27 skills. Unit 1 Kinematics and introduction to dynamics. Unit 2 Newton's laws.

we see three equations to solve for power. in equation one P=I^2R this indicates power is directly proportional to current and resistance. However, in the third one we see that P=V^2/R this indicates power is directly proportional to voltage and inversely proportional to resistance, but how is that possible.

And since impulse is a change in momentum, and momentum is a vector, that means impulse is also a vector, so it can be positive and negative. And the units are the same as momentum, which is kilograms times meters per second. Or, since it's also force times time, you could write the units as Newtons times seconds. 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.
