Newton's 1st Law

Newton's Law

An object at rest stays at rest and an object in motion stays in motion with the same speed and in the same direction unless acted upon by an outside force.

I use Newton's 1st Law in my everyday life. I use it when I open doors, the door would stay shut unless I push it. When I play soccer I use Newton's 1st law. Unless I apply power to the ball it won't move.
