# Physics Summary

## Newton's First law of Motion- Inertia

An object at rest stays at rest and an object in motion stays in motion unless it is acted on by an unbalanced force. Force makes the object move, and force makes the object stop. The object is either in motion or not in motion. The object when still is full of potential energy, and when the object is in motion it is full of kinetic energy.

## Newton's Second law of Motion - f= m x a

The acceleration of an object occurs by the mass of an object and the applied force the object is moving at. The direction of the force is the same as the acceleration force. The acceleration of an object is created by force and the mass of an object, The energy when acted upon a force becomes motion, and the energy becomes kinetic.

## Newton's Third law of Motion - action / reaction

For every action there is an equivalent and opposite reaction. If an object is put in motion, the object will continue to be in motion, that is the reaction. The force moves the object, the energy is in the object's motion, and the amount of force used is in the law to put the object in motion is the relationship of force in the object.
