Gravitational potential energy is the energy an object has due to its position in a gravitational field.It can be calculated using the equation: ΔEp = mgΔh where Δh is the change in vertical height.For example a brick of mass 2.5kg lifted a vertical height of 3.2m will have increased its gravitational potential energy byΔEp = 2.5 ×9.81× 3.2= 78.5J (3 s.f.)
