Does a track at which a car is on, affect the speed of the car? There are many different kinds of angles for tracks, they can be heading downhill, uphill, or can be straight. Sometimes the angle of the track determines the speed of the car. Potential and kinetic energy will also have an effect of the car's speed. Potential energy is taken in when the car goes up, and kinetic energy is released when the car goes downhill. I think that when the car goes down, it will go faster do to the kinetic energy that is being released. The independent variable in this experiment is the angle of the track and the dependent variable is the car’s speed. Do items in a car affect the speed of a car? Cars are used transport people and many things, such
