3. If an object is moving, is it possible for the net force acting on it to be zero? Explain. 4. If the acceleration of an object is zero, are no forces acting on it? Explain, 5. Only one force acts on an object. Can the object have zero acceleration? Can it have zero velocity? Explain. 6. When a golf ball is dropped to the pavement, it bounces back up. (a) Is a force needed to make it bounce back up? (b) If so, what exerts the force?
