How does potential energy change in a gravitational field?

• A. Gravitational potential energy stays constant regardless of height.
• B. Gravitational potential energy decreases as an object's height increases.
• C. Gravitational potential energy increases as an object's height increases, calculated as PE = mgh.
• D. Gravitational potential energy is independent of mass.

Answer: (C)

Gravitational potential energy is directly related to an object's height in a gravitational field. As an object is lifted to a higher elevation, its gravitational potential energy increases. This relationship is quantified by the formula PE = mgh, where PE represents the potential energy, m is the mass of the object, g is the acceleration due to gravity, and h is the height above a reference point. Thus, when the height (h) of an object increases, it directly results in an increase in potential energy. This is because potential energy reflects the work done against gravity to raise an object to a certain height. In a gravitational field, as height increases, the work done to lift the object also increases, leading to higher potential energy. This understanding is crucial for grasping concepts related to energy conservation, mechanics, and how forces act on objects within a gravitational field.
