|---|---|
| inertia | the tendency of an object to resist a change in motion |
| newton's first law of motion | states that if the net force acting on an object is zero, the motion of the object does change |
| newton's second law of motion | states that the acceleration of an object is equal to the net force applied to the object divided by the object's mass |
| newton's third law of motion | says that when one object exerts a force on a second object, the second object exerts a force of the same size, but in the opposite direction, on the first object |
| force pair | when two objects exert forces on each other |
