... Physics Course work Car on a ramp By Ben Sweeney Aim: The aim of this investigation is to see if the height of a ramp affects the speed of a car pushed down it. Prediction: I predict that as the height of the ramp increases the potential energy of the car goes up. Science dictates that potential energy is affected by height. This is shown by the heights presence in the equation for potential energy: potential energy = weight x gravity x height joules = grams x Newton's x centimetres Kinetic energy is the movement of the car from the potential energy. So as the kinetic energy is used the potential energy goes down. Also, as the potential energy increases the kinetic energy increases similarly. I predict that as the ramp gets higher the car will move faster down the slop. I think this because science dictates that gravity pulls a mass towards it, and as the ramp gets
