    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

    where:

    m = mass

    g = acceleration due to gravity

    z = height

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