A 8-kg object moves vertically a distance of 3 m. Its potential energy has changed by approximately how much?

Question

Quizplus · Accepted Answer

The change in potential energy is given by the formula: ΔPE = mgh, where m is the mass of the object, g is the acceleration due to gravity, and h is the height through which the object moves. In this case, m = 8 kg, g = 9.8 m/s^2, and h = 3 m. Plugging these values into the formula, we get: ΔPE = (8 kg)(9.8 m/s^2)(3 m) = 240 J. Therefore, the potential energy of the object has increased by 240 J.
