The purpose of this activity is to investigate the relationship between the speed of a toy car just prior to hitting a box and the distance that the car and the box slide before stopping. In the simulation, a toy car will be released from the top of an inclined plane from a given height. It will accelerate to the floor where its speed will be measured. The car will then collide with a small box. The box and the car will slide across the floor to a final stopping position. The initial height of the car can be modified. The speed of the car prior to striking the box will be reported. The sliding distance of the car can be measured.
