________ is energy that is stored in an object as a result of its position, shape, or chemical composition.

• Chemical

• Mechanical

• Kinetic

• Potential

The amount of elastic potential energy stored is related to the amount of stretch of the object; the more stretch the more energy.

• true

• false

What is the formula for work?

• F = M(A)

• W = F(D)

• KE = 1/2M (V)2

• Power = W/T

States that energy cannot be created or destroyed,

only transformed/transferred.
