1. The problem statement, all variables and given/known data 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 dont understand the relationship between angle of incline, velocity and gravity. Basically, how does increased gravitational PE affect velocity? 2. Relevant equations mgh 2s/t=v 3. 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!
