You will be given a velocity vs. time graph for the motion of a car. Your job is to match the graph with your car by pushing on the gas or brake or coasting at the appropriate moments. Before you start the matching game, you must set the proper starting speed and the proper accelerations.
If you select desktop version, you must click and hold the gas pedal and/or the brake pedal to control the car.
If you select touch version, you must touch and release the gas pedal or the brake pedal to activate and touch and release the pedal again to deactivate.
