First and Second Law of Motion

The tendency of an object to resist a change in motion:

• Momentum

• Gravity

• Inertia

• Force

Objects at rest will stay at rest and objects in motion will stay in motion unless acted upon by an outside force:

• 1st law

• 2nd law

• 3rd law

Acceleration depends on the object's mass and the net force acting on the object:

• 2nd part of 1st law

• 2nd law

• 3rd law
