How much does the potential energy of a body weighing 500 g increase when rising to a height of 40 cm?

univerkov | June 23, 2021 | education

Initial data: m (mass of the body lifted to a given height) = 500 g (0.5 kg); Δh (change in body height) = 40 cm (0.4 m).

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

The increase in the potential energy of the body can be calculated by the formula: ΔEp = m * g * Δh.

Calculation: ΔEp = 0.5 * 10 * 0.4 = 2 J.

Answer: When lifting to a given height, the potential energy of the body will increase by 2 J.
