A stone with a mass of m = 0.5 kg fell from a balcony with a height of h = 4m.

A stone with a mass of m = 0.5 kg fell from a balcony with a height of h = 4m. The modulus of changing the potential energy of the stone is equal.

To find the modulus of change in the potential energy of a given stone, we apply the formula: ΔEp = m * g * h.

Constants and variables: m is the mass of the stone (m = 0.5 kg); g – acceleration due to gravity (g ≈ 10 m / s2); h – the height of the balcony, the initial height of the stone (h = 4 m).

Let’s perform the calculation: ΔEp = m * g * h = 0.5 * 10 * 4 = 20 J.

Answer: The modulus of changing the potential energy of a given stone is 20 J.
