Explain how bumper cars are an example of Newton's Third Law of Motion.

Bumper cars are a great example of Newton's Third Law of Motion, which states that for every action, there is an equal and opposite reaction. In the context of bumper cars, when two cars collide, they exert forces on each other.

The correct choice is:

**C. When bumper cars collide, they will bounce apart with equal force.**

This answer reflects that the force exerted by one car on the other is matched by an equal force exerted in the opposite direction by the second car. Thus, both cars will experience equal and opposite forces during the collision, leading them to bounce apart.
