What work does the force of gravity do when a stone with a mass of 0.5 km and a height of 15 m falls?

Given: m (the mass of the fallen stone) = 0.5 kg; h (the height from which the stone in question began to fall) = 15 m.

Constants: g (acceleration due to gravity) ≈ 10 m / s2.

We calculate the work done by gravity when the stone in question falls by the formula: A = Ft * S = ΔEp = m * g * h.

Let’s calculate: A = 0.5 * 10 * 15 = 75 J.

Answer: When the stone in question fell, gravity did a work of 75 J.
