What is Newton’s First Law of Motion?
Friction is the only force that will act upon a body within the earth’s atmosphere.
Once a body is acted upon it remains in motion.
Every body remains in uniform motion at all times.
Every body remains in a state of rest or uniform motion unless acted upon by a net external force.
What is Newton’s Third Law of Motion?
For every action there is an equal and opposite reaction.
Every body remains in a state of rest or uniform motion unless acted upon by a net external force.
Momentum is the key to accelerating a body and decelerating it.
The amount of acceleration of a body is proportional to the acting force and inversely proportional to the mass of the body.
What is Newton’s Second Law of Motion?
The amount of acceleration of a body is proportional to the acting force and inversely proportional to the mass of the body.
Every body remains in a state of rest or uniform motion unless acted upon by a net external force.
For every action there is an equal and opposite reaction.
The force of gravity acting on an object is constant.
