# Newton's Laws of Motion

## How Were the Laws Created?

Isaac Newton was one of the greatest scientists that ever existed. In 1666, the fall of an apple led him to the great discovery of the laws of gravitation. His ideas gave explanation towards the strange forces of gravity and motion. The new laws could clearly show how force affects the motion of an object. These well known, world wide theories help give many answers to scientific questions and calculations over the years.

## Newton's Law of Inertia

An object at rest will stay at rest unless acted upon by an unbalanced force.

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

Inertia: an object's tendency to resist change in motion (The greater an object's mass is, the greater its inertia)

## Newton's Law of Acceleration

The acceleration of an object by a force is inversely proportional to the mass of the object and directly proportional to the force applied.

The acceleration of the object depends on the mass of the object and the amount of force applied to the object

## Newton's Law of Action/Reaction

For every action, there is an equal and opposite reaction.

An action force causes a reaction force that is equal in size and opposite in direction.

## One Last Thing...

If you didn't notice before, I purposely made the background of this poster a golf course. This is because, in this location, all three laws of motion take place.

Law 1: The golf ball sits at rest on the tee until the golfer (unbalanced force) hits the ball, sending it flying in motion.

Law 2: Two golf balls with the same mass land in two different spots on the green because one was hit with more force than the other, causing it to accelerate more.

Law 3: When the golf ball lands on the ground after flying, it bounces back in the air with an equal and opposite reaction it had as it landed on the ground.
