Question

1. Consider the forces acting on a car. When a car is accelerating, it will move in the direction of the net force. This is because the force of the engine is large enough to overcome the forces of friction and air resistance. However, objects do not always move in the direction of the net force. Explain how this would be the case for a car coming to a stop at a traffic light. Your answer should include a diagram showing the forces acting on the vehicle.

Answer 1

Objects always move in the direction of their velocity, not acceleration.
