IntroductionMovement is a familiar everyday word that we use in place of movement. Motion is a change in the position of an object in relation to the direction it has gone and time. The movement was explained by a now famous scientist who goes by the name of Issac Newton. He invented the 3 laws of motion. The law we will focus on is Newton's first law, often called “Newton's first law of inertia”. Newton's first law is commonly stated as "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 an external force intervenes." Simply put, a moving object will continue to move in the same direction and at the same speed unless another force acts on it, and a non-moving object will not start to move unless there is a other force acting on it. Inertia is the term scientists use to describe the way objects resist change in their motion. Inertia is directly related to the mass of an object. The greater the mass of an object, the greater its inertia. In other words, the heavier an object is, the more resistant it is...
