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, making the parked car move (gain kinetic energy). Energy is transferred, not created or destroyed (so the moving car's kinetic energy doesn't disappear, and the parked car's kinetic energy isn't created from nothing, and the parked car can't transfer kinetic energy it doesn't have to the moving car).

Answer:

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