How is angle of incline related to the acceleration of the car moving down it?
I know how to find both the velocity and acceleration of a car moving down a track using the suvat equations. I don't understand the relationship between angle of incline, velocity and gravity.
Basically, how does increased gravitational PE affect velocity?
The Attempt at a Solution
I think it has something to do with cosine of the angle as well as 1/2mv^2
Thank you guys and Gals!
