•
#1
A body remains at rest, or moves with
constant velocity unless acted upon by an
outside force
•
#2
The change in a body’s velocity due
to an applied force is in the same direction
as the force and proportional to it, but is
inversely proportional to the body’s mass.
F = m a
•
#3
For every applied force, a force of
equal size but opposite direction arises.
Weight
•
One example of a force.
•
W=mg
•
g=acceleration due to gravity at Earth’s
surface = 9.8 m/s/s
