| first law of motion | if the net force acting on an object is zero, an object in motion stays in motion and an object at rest stays at rest. |
| inertia | the tendency of an object to resist a change in motion |
| second law of motion | the relationship among force, mass, and acceleration |
| f=ma | formula for second law |
| centripetal acceleration | acceleration toward the center of a curved path |
| centripetal force | a force that moves an object in the direction of the center of a curved path |
| gravity | an attractive force between any two objects |
| weight | the gravitational force placed on an object |
| w=mg | formula for weight |
| momentum | the product of a moving objects mass and velocity |
| p=mv | formula for momentum |
| third law of motion | for every action there is an equal and opposite reaction |
