Newton's first law | An object in motion (or at rest) will tend to stay in motion (or at rest) until it is acted upon by an outside force. |
Inertia | The tendency of an object to resist changes in its velocity. |
Friction | A force that opposes motion, resulting from the contact of two surfaces. |
Static Friction | Friction that opposes the initiation of motion. |
Newton's Second law | When an object is acted on by one or more outside forces, the total force is equal to the mass of the object times the resulting acceleration. |
Kinetic Friction | Friction that opposes motion once the motion has already started. |
Newton's third law | For every action, there is an equal and opposite reaction. |
