What is Inertia?

Inertia is a very important part of our lives that we are part of everyday but don’t think about. Galileo Galilei, a famous Italian scientist discovered it. Sir Isaac Newton, who was a scientist in England in the 1600’s discovered many things about math and science. He came up with the Laws of Motion which tell us the ba-sics of how things move. The First Law of Motion has to do with inertia. This Law of Motion says: “An object in motion will continue to stay in motion unless acted upon by an outside force.” In other words, if something is moving, it will keep moving until something stops it. If something is NOT moving, it will just sit there until something else comes along and moves it. That’s inertia!
