Question

what happens in terms of energy when a moving car hits a parked car, causing the parked car to move?

the moving car transfers kinetic energy to the parked car.

kinetic energy in the moving car disappears.

kinetic energy in the parked car is created.

the parked car transfers kinetic energy to the moving car.

Explanation:

Kinetic energy is the energy of motion. A moving car has kinetic energy. When it hits a parked car (which initially has no kinetic energy as it's stationary), the moving car transfers its kinetic energy to the parked car, causing the parked car to move (gain kinetic energy). Energy is transferred, not created or destroyed (so the option saying kinetic energy disappears is wrong, and energy isn't created in the parked car). Also, the parked car is initially stationary, so it can't transfer kinetic energy to the moving car.

Answer:

A. The moving car transfers kinetic energy to the parked car.
