Newton’s first law of motion: an object at rest will remain at rest unless acted on by a force. An object in motion continues in motion with the same speed and in the same direction unless acted upon by a force. This law is often called, "the law of inertia". Newton observed how objects moved. He studied how forces like gravity changed the motion of an object. He found that forces change when the speed or mass of an object changes. Today these same laws of motion are being used when we play sports. Newton’s laws are demonstrated when a goal is scored in soccer, a baseball hit with a bat, or a three point basket is made on the court.
Examples of Newton’s Laws are found in our machines, work, homes and sports. .
