| Newton's 2nd Law of Motion | Force = mass X acceleration |
| Friction | the force that opposes the sliding motion between two touching objects |
| Static friction | frictional force that prevents 2 surfaces from sliding past one another |
| Sliding friction | frictional force that opposes motion of 2 surfaces sliding past one another |
| Air resistance | force that opposes the motion of objects that move through the air |
| Gravity | attractive force between 2 objects that depends on the masses of the objects and the distance between them |
| Centripetal acceleration | acceleration of an object toward the center of a curved or circular path |
| Centripetal force | a net force that is directed toward the center of a curved or circular path |
| Newton's 3rd Law of Motion | for every action there is an equal and opposite reaction |
| Weight | gravitational force exerted on an object |
| Momentum | The property of a moving object that equal mass X velocity |
| Isaac Newton | Scientist who studied in england and introduced several laws describing force nad motion |
| inertia | the tendency of an object to resist a change in motion |
| projectile | an object upon which the only force acting is gravity |
| Conservation of Momentum | States that the total momentum of the two objects before the collision is equal to the total momentum of the two objects after the collision. That is, the momentum lost by object 1 is equal to the momentum gained by object 2 |
