What is the gravitational potential energy of a ceiling fan that has a mass of 7 kg and is 4 m above the ground?

The gravitational potential energy of the ceiling fan can be calculated using the formula: GPE = mgh, where m is the mass (7 kg), g is the acceleration due to gravity (9.81 m/s^2), and h is the height (4 m). Plugging in the values: GPE = 7 kg * 9.81 m/s^2 * 4 m = 274.68 Joules.
