Physics

• work done
• Time interval 

the energy due to the position of something or the movement of something

the energy that is stored and held in reading it

weight X height ( PE = mgh) 

1/2 mass X speed squared 

depends on the mass of the object as well as its speed

kinetic energy

Change (KE) 

work equip change in kinetic energy

the effort exerted on something that will change its energy

force X distance

energy cannot be created or destroyed it may be transformed from 1 form into another but the total amount of energy never changes

• useful energy output 
• Total energy input
