What is the first law of motion proposed by Isaac Newton?
An object at rest stays at rest and an object in motion stays in motion unless acted upon by a net external force.
Force equals mass times acceleration.
For every action, there is an equal and opposite reaction.
The acceleration of an object is directly proportional to the net force acting upon it.
According to Newton's Second Law, how is acceleration calculated?
Force divided by mass.
Mass divided by force.
Force times mass.
Force minus mass.
What does Newton's Third Law state?
For every action, there is an equal and opposite reaction.
An object in motion will stay in motion.
Acceleration is produced when a force acts on a mass.
The path of a projectile is a parabola.
