Potential Energy Wiki Video
Definition:
Potential energy is the stored energy of position possessed by an object.


Explanation/Notes:
An object can store energy as the result of its position. This form of energy has potential to change state of other objects around it. Gravity gives potential energy to any object.


Formula:
PE= Potential Energy
m=Mass
g=gravity
h=height

Units:
m=grams
g=9.8 m/s squared
h=meters

Everyday Example:
An example for potential energy is when a heavy ball of a domolition machine is storing energy in position or a swing.

Sample Problem:

Calculate the gravitational potential energy of a 10 kg sack of groceries on a shelf 1 meter above the floor?

PE=(m)(g)(h)

PE=(1 m)(9.8 m/s)(10 kg)

PE=98 Joules
