First Law of Motion

First Law of Motion

What is it?
Sir Isaac Newton's First Law of Motion states that an object in motion will remain in motion, or an object at rest will remain at rest, until it is acted upon by some outside force.
"An object at rest will remain at rest unless acted upon by an external and unbalanced force. An object in motion will remain in motion unless acted upon by an external and unbalanced force."

Give me an example!

Think of a bowling ball as your particle. If it is just sitting there and nobody bothers it, it would remain sitting there. And if the bowling ball is rolling on a straight and level surface and nobody bothers it, it would keep right on rolling in a straight line.
