What is unbalanced
An object in motion stays in motion and an object at rest stays at rest unless acted on by an unbalanced force. Ex. When a car stops quickly, everything in the car flies forward.
What is Law of inertia
F =mass x acceleration. Use Force Triangle (force on top). Ex. An object with a greater mass accelerates less than an object with less mass.
What is the Law of force and motion
For every action, there is an equal but opposite reaction. Ex. Action - A book pushes down on a desk. Reaction - Desk pushes up on book.
