Newton's Laws

"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."

"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)."

ALL THREE LAWS

THE FIRST LAW OF MOTION

The elephant is heavy and therefore requires more force to push.

(Also called Inertia!)

THE SECOND LAW OF MOTION

Newton's Laws of Motion

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