"Objects in motion will stay in motion,
objects at rest will stay at rest,
unless acted upon by an unbalanced force."
The Law of Inertia
The Law of Acceleration
The Law of Action and Reaction
"The acceleration of an object with constant mass
is proportional to the net force action on it and
in the same direction of the net force."
The Law of Inertia
The Law of Acceleration
The Law of Action and Reaction
"Every action force has a reaction force that is equal in size and opposite in direction."
