Newtons Laws

By Abigail Powell

Who was Isaac Newton?

Isaac Newton is the creator of the 3 laws of Motion. He was also an English Physicist and a Mathematician.

The 1st Law of Motion

The first law of motion states that an object at rest will stay at rest and an object in motion will stay in motion with the same velocity unless acted upon by an unbalanced force.

What does that mean?

This means that if you were to roll a ball with nothing in it's way the ball would never stop rolling, unless there was something there for it to run into. That would be your unbalanced force. This also means that if you were to place a ball in the grass it would not move because there is no unbalanced force to move it. If you were to kick or throw that ball then you would be the unbalanced force that the ball is acted upon by.

The 2nd Law of Motion

The acceleration of an object increase with increased force decreases with increased mass.

What Does That Mean?

That means that more mass is less acceleration and less mass is more acceleration.

Newtons 3rd Law

For every action there is an equal and opposite reaction.

What does that mean?

That means that if you were to throw a ball in the air then it will come down. Throwing the ball would a the action and the reaction would be it coming down due to gravity.
