What is the potential energy of a vessel with water at a height of 80 cm if the mass of the vessel is 300 g?

The potential energy of a vessel with water (in the Earth’s gravitational field) can be calculated using the formula:
Ep = m * g * h, where Ep is the potential energy of the vessel with water (J), m is the mass of the vessel with water (m = 300 g = 0.3 kg), g is the acceleration of gravity (we take g = 10 m / s²), h is the height of the vessel with water relative to the ground (h = 80 cm = 0.8 m).
Let’s calculate the potential energy:
Ep = m * g * h = 0.3 * 10 * 0.8 = 2.4 J.
Answer: The potential energy of a vessel with water is 2.4 J.
