What is Potential Energy?
Energy that is stored and waiting to be used laterSlide4
What is Gravitational Potential Energy?
Potential energy due to an object’s position
P.E. = mass x
height x gravity
Don’t look down, Rover!
Good boy!Slide5
What is Elastic Potential Energy?
Potential energy due compression or expansion of an elastic object.
Notice the ball compressing
and expandingSlide6
What is Chemical Potential Energy?
Potential energy stored within the chemical bonds of an objectSlide7
What is Kinetic Energy?
Energy an object has due to its motion
K.E. = .5(mass x speed

THE TRADE OFF Between Potential & Kinetic Energy

Law of Conservation of Energy
Law of Conservation of Energy- Energy can neither be created nor destroyed. Energy is always changing from one kind to another. The total energy of an object never changes
.
Conservation of energy states that
Ki
+ Pi =
Kf
+ Pf
.
This simply means that the sum of the skiers initial potential and kinetic energy is equal to the sum of the skiers final potential and kinetic energy.
