Newton's 1st Law of Motion
An object moving in a straight line will continue moving ina straight line, unless acted on by an outside force. Also, an object at rest will stay at rest. The word for this is inertia.
Newton's 2nd Law of Motion
Force will cause a change in the otion of an object. The change in motion depends on the smount of force and the mass of the objec. There is a formula for this F = ma (Force = Mass X Acceleration.
Newton's 3rd Law of Motion
For each action, ther is an equal and opposite reaction.
