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 |
