Newton`s Laws of Motion
... Every body will persist in its state of rest or its state of uniform motion in a straight line unless that state is changed by forces impressed upon it. This is often called the Law of Inertia. (Inertia is a property of all matter…..matter resists having its state of motion changed. Mass is the meas ...
