Energy Work and Power

______ Is done when a force (N) causes an object to move a certain distance (m).

• Energy

• Work

• Power

• Force

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

• Chemical

• Kinetic

• Mechanical

• Potential

_________ is Active energy; the energy associated with the movement of objects. Anything that is moving has _________.

• Kinetic Energy

• Potential Energy

• Gravitational Energy

• Mechanical

The formula for Kinetic Energy is:

• KE = ½ mv2

• KE = FD

• KE = 1/2 FD2

• KE = M x A

________ Is energy stored in elastic materials such as a spring (when it’s compressed) or elastic object (when it’s stretched).

• Gravitational Potential Energy

• Mechanical

• Elastic Potential Energy

• Chemical

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)

• KE = 1/2M (V)2

• W = F(D)

• Power = W/T

States that energy cannot be created or destroyed,

only transformed/transferred.
