Physical Sci. Motion and Force

A force action on an object causes the object to acclerate in the direction of the force.

• Law of Momentum

• Newtons 2nd law

• Newton 1st law

• Newtons 3rd law

Every action has an equal and opposite reaction

• Law of Momentum

• Newtons 2nd law

• Newton 1st law

• Newtons 3rd law

An object in motion will stay the same until a force acts on it

• Law of Momentum

• Newtons 2nd law

• Newton 1st law

• Newtons 3rd law

Motion is a change in

• Velocity

• Position

• Place

• Form
