This document introduces potential energy as energy that an object has due to its position or arrangement. Potential energy is stored energy or stored work that can be calculated using the formula PE = mgh, where m is mass, g is acceleration due to gravity, and h is height. The document explains that potential energy is sometimes not directly converted to kinetic energy but instead stored, and provides steps for calculating potential energy by setting a reference point where potential energy is equal to zero and determining the negative work done by conservative forces.

7. Potential Energy
 Potential energy is energy that an
object (system) has due to its position
or arrangement.

8. Potential Energy
 Sometimes work is not converted
directly into kinetic energy. Instead it is
“stored”, or “hidden”.
 Potential energy is stored energy or
stored work.

9. P.E. = mgh
m – mass of the body
g – acceleration due to gravity
h - height

10. Calculating Potential Energy
 To calculate the potential energy of a
particular arrangement:
1. Pick a position or arrangement that
you want to call the “potential energy
= 0” situation.

11. Calculating Potential Energy
2. The potential energy of any other
position or arrangement equals the
negative of the work that the
conservative force does in changing
from the potential energy = 0 situation
to that one.
PE = - WorkF
