Newton's Laws of Motion

By Joshua Rogers

Newton's Laws of Motion

Newton's first law of motion says that an object in motion will stay in motion and an object at rest will stay at rest unless acted upon by an external force. Inertia is the resistance to change in an object's motion. The greater the mass of the object, the greater it's inertia.

Law #3

Newton's third law of motion states that for every action there is an equal and opposite reaction. In other words, when an object applies force to another object, the second object applies the same amount of force to the first object, only in the opposite direction. This is also called action/reaction because the second object is reacting to the first action.

Law #2

Newton's second law of motion states that the force of an object is equal to its mass times its acceleration. (f = ma) An object will only move if a net force is exerted on it. When a net force is exerted on an object, the object will move in the direction of the force. If the force acting upon the object stays the same, more mass equals less acceleration.
