Newton’s 1 st Law of Motion

The Law An object at rest tends to stay at rest and an object in motion tends to stay in motion unless acted on by an unbalanced force.

Free Body Diagrams

Question If objects in motion tend to stay in motion, why don’t they keep going forever? Unbalanced Forces!!! What are some examples of forces that can act upon an object?

Friction

Gravity

Inertia Inertia is how much an object will resist a change in motion More mass means more inertia
