NEWTON’S LAWS
1st
NOTES
2nd
3rd
Objects in motion stay in motion and objects at rest
stay at rest unless acted upon by an unbalanced
force.
F = m* a
For every action
there is an equal
and opposite
reaction.

FORCESEXAMPLE 1
1. You are attempting to move a box of cats
across the ground. If the box has a mass of
14kg, and the coefficient of static friction is
0.68, how much force must you apply to move
the box? You must apply at least
93.30 N of force to move
the box.

2. You are moving a box of puppies across the
ground with a force of 100N. If the box has a
mass of 23kg, and the coefficient of kinetic
friction is 0.33, what is the acceleration of the
box? The box of puppies has an
acceleration of 1.11 m/s2
in the x direction.
