There are four new words this week- the remaining 6 will be recycled from last week. The new words are:

mechanical energy: the energy of movement caused by forces

Force: A push or a pull

Friction: a force that works against movement. Rough surfaces have a lot of friction, and do not allow objects to move easily across them. This is the opposite for smooth surfaces.

Work: only happens when an object moves because of a force.

EDIT: THERE WILL BE NO VOCABULARY QUIZ THIS WEEK

----they will resume next week.
