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).

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
