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 |
Kinetic friction | Friction that opposes motion once the motion has already started |
Static friction | Friction that opposes the initiation of motion |
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 |
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 |
Newton's Third Law | For every action, there is an equal and opposite reaction |
