The First Law of Motion is
First Law Law of Inertia

• The laws states An object in motion tends to
  stay in motion and an object at rest tends to
  stay at restunless acted on by an outside
  force.

What are some important details about the first
law?

• Inertia is the property of an object to maintain
  its current state of motion.

• Inertia is closely related to mass.

• A force must occur to change an objects speed
  and/or direction.

• Friction is a common force that causes objects to
  slow down.

The Second Law of Motion is
Second Law Law of Acceleration

• The law states Force equals mass times
  acceleration.

• F ma

What are some important details about the second
law?

• This law is the mathematical relationship between
  force, mass, and acceleration.

• F stands for the net force. Be sure to calculate
  the net force first.

• If mass is the same, force and acceleration are
  directly proportionalwhich means

• If force is the same, mass and acceleration are
  inversely proportionalwhich means

The Third Law of Motion is
Third Law Law of Action/Reaction

• The law states For every action there is an
  equal and opposite reaction.

• To find action/reaction pairs use the following
  recipe

What are some important details about the third
law?
A exerts a force on B. B exerts a force on A.

• Action/reaction pairs are always equal and
  opposite.

• Action/reaction pairs act on different objects.

• Action/reaction pairs do not cancel out.

The Third Law of Motion is
Third Law Law of Action/Reaction

• Although the forces are the same, differences in
  mass cause differences in accelerationswhich is
  what we perceive when looking at a situation.

(a.k.a. Law of Inertia)
An object in motion tends to stay in motion, and
an object at rest tends to stay at restunless
acted on by an outside force.
