Examine the system model below, which shows a car moving along a track at two different points in time. Assume there is no friction between the car and the track. In the before image, a car is moving along a track at a constant speed towards a motionless wheel.
Use your knowledge of the transfer of energy to complete the claim below to describe what causes the wheel to spin after contact with the car. Then, complete your scientific explanation by supporting your claim with evidence and reasoning.

In the after image, the car has contacted the wheel, which begins to spin. The car continues to travel along the track at a slower speed.
