Energy Review Qtr 2 Part 1

What is conservation of energy?

• Conservation of energy says that energy isn't created or destroyed, it can only move from one object to another, but not from one type of energy to another.

• Conservation of energy says that energy isn't created or destroyed, it can only move from one object to another, or from one type of energy to another.
