... What two things can you say about an object’s motion if the net forces on the object are zero? Which of these objects are accelerating? a. A ball that is falling. b. A rocket flying at a constant velocity through space. c. A car traveling down the road at a constant velocity. d. A book resting on a ...

... pushing up. Air might be blowing on the ball, but friction is pushing back. The ball is in equilibrium. In mathematical notation: Fnet = 0, the net force is zero, or ∑F = 0, the sum of forces is zero. If the forces on the ball didn't equal out, then the ball would start moving; it would accelerate ( ...
