      Potential Energy (P.E) is the energy associated with the position of a body relative to the earth's surface. For example, lifted masses above the earth's surface possess potential energy. The term "potential" means “stored”. The potential energy of a body of mass (m) lifted to a height of 'h' above the ground is mathematically expressed as:

Potential energy is energy due to the position or shape of an object. Usually, it is the change in potential energy that is the important quantity, not any particular value of the potential energy.

      The units of the shaft work appear to be strange, but they are not. Let us investigate this further. Recall that each term in this version of the Engineering Bernoulli Equation must have the same units as the loss or shaft work, which are in energy per unit mass flowing through the control volume.

      A book resting on the edge of a table has potential energy; If you bet push it over the edge, the book would fall. It is sometimes called gravitational potential energy (PE). It can be expressed mathematically as follows: PE - mass x g x height or PE - weight x height where PE is the potential energy, and g is acceleration due to gravity.
