Final answer:
The movement of bumper cars supports Newton's second law of motion as the change in motion of a body is proportional to and in the direction of the force acting on it.
Step-by-step explanation:
According to Newton's second law of motion, the change of motion of a body is proportional to and in the direction of the force acting on it. In the case of bumper cars, when a person applies a force to the car by bumping into it, the car will experience a change in motion in the direction of the force applied. The magnitude of the change in motion, or acceleration, will depend on the mass of the car and the magnitude of the force.
For example, if a heavier car collides with a lighter car, the force of the heavier car will cause a greater change in motion, or acceleration, on the lighter car compared to the heavier car. This demonstrates Newton's second law of motion, which states that the acceleration of a system is directly proportional to and in the same direction as the net external force acting on the system, and inversely proportional to its mass.
