NEWTON’S LAWS
I. If a balanced force system acts on a
particle at rest, it will remain at rest. If a balanced force system
acts on a particle in motion, it will remain in motion in a straight
line without acceleration.
II. If an unbalanced force system acts
on a particle, it will accelerate in proportion to the magnitude and
in the direction of the resultant force.
III. When two particles exert forces on
each other, these forces are equal in magnitude, opposite in
direction, and collinear.
