Newton's First Law
Law of Inertia
What is Newtons 1st Law ?
Newton’s 1st law is objects at rest and objects in motion stay at motion unless acted on by a net force.
The pictures demonstrate Newton 1st law. The picture on the right is showing the golf ball at rest on a toilet tissue roll. The picture on the left is showing the coin at rest but the man hand is in motion acted on by a net force.
