Question

Calculate the gravitational potential energy of the interacting pair of the Earth and a 11 kg block sitting on the surface of the Earth. You would need to supply the absolute value of this result to move the block to a location very far from the Earth (actually, you would need to use even more energy than this due to the gravitational potential energy associated with the Sun-block interacting pair).

    Answer:

    Gravitational potential energy (GPE) = 107.8J

    Explanation:

    Gravitational potential energy (GPE) = mgh

    Where mass(m) = 11kg

    Acceleration due to gravity(g) = 9.8m²/s

    height = assumed to be 1m

    Force(F) = mg

    Force(F) = 11×9.8 = 107.8N

    Gravitational potential energy (GPE) = 107.8×1

    = 107.8J
