Motion
What is acceleration?
The rate of change in velocity.
What is Inertia?
The force that is stopping you from moving.
What is force?
A push or pull one body exerts on another.
What is Work?
An object begins to move only when unbalanced forces act on it.
What is Energy?
The ability to cause change.
What is speed?
The rate of change of position of an object in any direction.
What is Newton's Second law of motion?
The force acting on an object is equal to the mass x the acceleration caused by the force

What is Newton's First Law of Motion?
An object at rest remains at rest, and an object in motion remains in motion at constant speed and in a straight line unless acted on by an unbalanced force.
