What happens to an object's speed when it experiences positive acceleration? a) It stays the same b) it decreases c) it increases d) it moves backward 9) 9. If an object has zero acceleration, what does that mean? a) The object is moving at a constant velocity. b) The object is speeding up. c) The object is slowing down. d) The object is falling due to gravity. 10) 10.
