• friction/gravity

• momentum/time

• distance/time

Inertia is....

• for every action, there is an equal and opposite reaction

• larger objects take more force to move 

• an object in motion tends to stay in motion unless acted on by an opposite force

• a push that acts in the opposite direction and it slows down.

Acceleration and Force

• the more force you apply, the greater the inertia

• the more force you apply, the greater the momentum

• the more force you apply, the greater the friction

• the more force you apply, the greater the acceleration
