The potential energy of a body at a height of 3m is equal to 14 J. What will be its potential energy

The potential energy of a body at a height of 3m is equal to 14 J. What will be its potential energy when the height increases to 6m.

The potential energy (Ep = m * g * h) depends on the mass of the taken body (m) and its height (h) above the zero surface (the acceleration of gravity (g) at heights near the Earth’s surface will be constant). Since the body mass for this task is constant, the potential energy will increase only due to an increase in height. Since the height of the body has increased 2 times (6/3 = 2), then the potential energy of the body has increased 2 times (En = 2 * 14 = 28 J).
Answer: The potential energy will increase to 28 J.
