Choose the correct statement in the parentheses. • If an object has a constant velocity, there (must, may, or cannot) be a net force acting on it. • If an object accelerates, there (must, may, or cannot) be a net force acting on it. • If an object remains at rest, there (must may, or cannot) be a net force acting on it. • If an object moves, there (must, may, or cannot) be a net force acting on it. • The less mass a moving object has, the (harder, easier, none of the above) it is to stop it. • The more mass an object at rest has, the (harder, easier, none of the above) it is to make it move. • The more mass a moving object has, the (harder, easier, none of the above) it is to keep it moving.
