Force and Motion
When you click the "Go" button an object moves across the screen. Think of it as a hockey puck moving without friction on ice, as viewed from above. As it moves it leaves "tracks" of a motion diagram. There may be a small net force on the puck in any one of eight compass directions, or the net force may be zero. Your task is to examine the motion diagram and determine what direction, if any, the net force is in.
