Answer:
Explanation:
"POTENTIAL ENERGY OF AN OBJECT"
Potential Energy =PE=m*g*h. If object is already in motion it acquires another kind of energy called Kinetic Energy. Formula for Kinetic Energy is: KE=1/2 mass * speed2.
For example: throwing a ball requires work to be done on the ball.
"LAW OF CONSERVATION OF ENERGY".
The law of conservation of energy is a law of science that states that energy cannot be created or destroyed, but only changed from one form into another or transferred from one object to another.
