What is inertia?
A tendency of an object to resist any change in its motion
A stable state of an object
The amount of force it takes to completely stop an object from moving
The amount of time it takes for an object to get from point A to point B
An object moving at a constant velocity keeps moving at that velocity unless a net force acts on it.
Newton's Second Law
Newton's First Law
Newton's Third Law
Not a law
What is Newton's Third Law
An object moves in the direction of the net force.
An object can not pull more than its own weight due to gravity.
For every action there is an equal opposite reaction.
