... B. If no net force acts on an object, the object will remain at rest, or continue to move at a constant velocity. C. The acceleration of freely falling objects is proportional to their mass. D. If a net force does act on an object, the object will accelerate in the direction of the net force. ...

Definition: A greater unbalanced external force causes greater acceleration of an object; Therefore, a greater unbalanced external force is needed to accelerate(speed up/slow down) an object of greater mass. Force = Mass X Acceleration Example: It takes more power to stop/move a heavier object than ...
