What is force?
Force is a push or pull on an object.
What is Newtons 1st Law of Motion?
An object at rest stays at rest, or an object in motion stays in motion until acted on by another force.

What is Acceleration?
Fast or slow speed in a short time.
What is Newtons 3rd Law of Motion?

What is Velocity?
Speed and Direction
What is Newtons 2nd Law?
Acceleration of an object that depends on the mass and force of the object.

What is a balanced force?
When an object is either at rest or in constant motion with no outside forces causing a change in movement.
What is Inertia?
The tendency of an object at rest to stay at rest unless it is acted upon by a force
What does no motion look like on an acceleration graph?
What is the Law of Conservation of Energy?
Energy is not created nor destroyed; It only changes from one form to another.
