Newton's Three Laws

Newton's Three Laws

First Law

An object at rest will remain at rest unless acted on by an unbalanced force. An object in motion continues in motion with the same speed and in the same direction unless acted upon by an unbalanced force.

Book's Def.

Acceleration is produced when a force acts on a mass. The greater the mass (of the object being accelerated) the greater the amount of force needed (to accelerate the object).

Book's Def.

For every action there is an equal and opposite re-action.

Book's Def.

Second Law

An object will maintain its path and velocity until a force forces its force upon it.

My Def.

The more mass an object has, the more force is needed to accelerate that object.

My Def.

Every action has an equal reaction in the opposite direction
