Net Force
... 1. The amount of matter in an object is called its weight. 2. The combination of all the forces on an object is called the net force. 3. Inertia is the reluctance any material object has to change in its state of motion. 4. Objects move only when a force is exerted. 5. The acceleration of an object ...
