Question

Carla pushes a toy car and lets it go. The toy car rolls and gradually comes to a stop. What would make the car stop?

A. A force must be applied to the car in the direction opposite to that in which it is moving.
B. A force must be applied pushing the car forward in the same direction as the moving car.
C. A force must be applied in a direction pushing the car upward to make the car stop.
D. A force must be applied in a direction pulling the car downward causing the car to stop.

Answer 1

A is correct because this creates friction so the car stops.

Answer 2

A is correct :) If you push up or down on a toy car it won't nessicarily stop. If you push it in the same direction, it will probably go faster. If you push it in the opposite direction, it will stop. (Or go backwards depending on how hard you push)
