Any Object at rest, or at a constant velocity, will stay at rest,
or at that velocity, unless acted upon by an outside force.
(for example friction or reality...aka physics gnomes)
Newton's Second Law of Motion:
May
the
F=mA be with you!
The relationship between an objects
mass (m) and any acceleration applied to it (A) is equal to the its force.
Newton's Third Law of Motion:
(physics gnome fight)
For every action there is an equal and opposite reaction!
