The action or process of moving or being moved.
Motion
The tendency of an object to keep moving (remain in its current state of movement).
Inertia
The forces pushing (or pulling) an object in one direction are the same size as the forces acting in the opposite direction.
Balanced force
Amount of matter in an object.
Mass
A push or pull that acts on an object.
Force
The forces on an object are pushing harder in one direction than in another, causing movement.
Unbalanced force
The speed of something in a given direction.
Velocity
The overall force acting on an object.
Net force
An increase in speed.
Acceleration
A type of force which pulls things towards the center of the Earth.
Gravity
The amount of gravity pulling down on an object.
Weight
Law of Inertia; Newton's First Law
An object at rest stays at rest AND an object in motion stays in motion unless acted on by an outside force
Newton's Second Law
Force is the product of mass and acceleration
Newton's Third Law
For every action there is an equal and opposite reaction
