Force is dependent upon two other factors. Name them.
What are mass and acceleration?
Name each law and a brief description of the law.
What are:
Law 1 - Law of inertia- object stays in motion or at rest until another force acts upon it.
Law 2- Force=Mass x Acceleration
Law 3- For every action there is an equal and opposite reaction.
