Forces #2

A forces is defined as a push or a pull. Today I'm going to talk about interita. Inertia is defined as an objects's ability to continue in the state is in. Inertia is proportional to the object's mass. For example if a bowling ball was to roll compared to a marble, the bowling ball would have more inertia than the marble. Newton's first law is the law that deals with inertia. It states that an object in motion will tend to stay in motion unless acted upon by an outside, unbalanced force. The same thing goes for objects at rest. Objects at rest will tend to stay at rest unless acted upon by an outside unbalanced force. An example of this is friction and gravity. Nothing on earth goes on forever because friction and gravity exists.
