“An object at rest will stay at rest and an object in motion will stay in motion.”

“For every action there is an equal and opposite reaction.”

When a piece of wood is sanded, the wood feels hot. The wood’s temperature rises because

heat stored in the wood is released.

The primary difference between speed and velocity is that

velocity includes direction, while speed does not

velocity increases, while speed does not change

velocity is based on distance, speed is not

speed includes direction, while velocity does not
