Chapter 5: Force and Motion I
If no net force acts on a body, then the
body’s velocity cannot change.
II. The net force on a body is equal to the
product of the body’s mass and
III. When two bodies interact, the forces on the
bodies from each other are always equal in
magnitude and opposite in direction.
