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.

Answer 1

The moving car transfers kinetic energy to the parked car.

Answer 2

The moving car transfers kinetic energy to the parked car.

Step-by-step explanation:

When moving car hits the car which is stationary in the parking then after collision the stationary car will start moving with some speed in the direction of the collision.

This is due to momentum conservation as per which we will say that since there is no external force on the system so here momentum of the system is being conserved

so here after collision both cars will move with either same speed together or they may move at different speeds.

So here the kinetic energy will be transferred to the other car.

so as per energy transfer terms we will say

The moving car transfers kinetic energy to the parked car.
