An object with a mass of 70 kilograms is supported at a height 8 meters above the ground. What's the potential energy of the object with respect to the ground?

The potential energy of an object is defined as the energy it harnesses as a result of the downwards pull of gravity. The acceleration due to gravity is equivalent to 9.8 m/s^2. Potential energy can be calculated using the formula: PE = mgz

m = mass
g = acceleration due to gravity
z = height

Therefore, for this problem, the PE = 70(9.8)(8) = 5488 Joules
