What is Newton's First law of motion?
An object at rest will stay at rest and an object in motion will stay in motion, unless unbalanced forces acts upon it
For every action their is an equal and opposite reaction
The acceleration of an object is equal to the net force acting on it divided by the objects mass
Which of the following is Newton's Second Law?
Acceleration depends on two variables, the mass of the object and the amount of force
An object at rest tends to stay at rest and an object in motion stays in motion unless acted upon by an outside force
For every action there is an equal and opposite reaction
Which of the following is Newton's 3rd Law?
An object at rest will stay at rest and an object in motion will continue in motion unless acted upon by an outside force
Acceleration depends on two variables, the mass of the object and the amount of force
For every action there is an equal and opposite reaction
Newton's second law is based on two variables, they are....

It will continue in random directions
It will stop immediately after leaving the astronauts hand
True or False: The action of throwing a rock would apply a force upon the astronaut throwing the rock.
True
False
