Elevation and potential energy

When a body of mass is elevated against the gravitational force the potential energy can be expressed as
Ep = Fg dh
= m g dh (1)
where
Fg = gravitational force (weight) acting on the body (N)
Ep = potential energy (J)
m = mass of body (kg)
g = gravitational acceleration (9.81 m/s2)
dh = change in elevation (m)
Example - Potential Energy when body is elevated
A body of 1000 kg is elevated 10 m. The change in potential energy can be calculated as
Ep = (1000 kg) (9.81 m/s2) (10 m)
= 98100 J
= 98 kJ
= 0.027 kWh
