The kinematic equation v² = u² + 2as is not directly applicable to objects moving with variable acceleration because it assumes a constant acceleration (a). For variable acceleration scenarios, calculus-based equations, such as those derived from the equations of motion or integrating acceleration functions, are more suitable. These equations can provide insights into the changing velocity and position of an object under varying acceleration conditions. Therefore, while v² = u² + 2as is powerful for constant acceleration situations, it has limitations in accurately describing the behavior of objects with acceleration that changes over time.

Potential energy is the energy an object possesses due to its position or condition, allowing it to do work when transformed into kinetic energy. It is defined as the energy stored within an object based on factors like its height, configuration, or state.

Potential energy is intimately related to the concept of work. Work (W) is done when a force is applied to an object, causing it to move over a distance. When a force acts against gravity, for instance, lifting an object against Earth’s gravitational pull, work is done, and the potential energy of the object increases. The work done (W) is equal to the change in potential energy (ΔPE). This relationship is expressed by the formula W = ΔPE. Thus, potential energy is a measure of the capacity to do work, and work done can lead to a change in an object’s potential energy.

In the context of the standard gravitational potential energy formula, GPE = mgh, gravitational potential energy (GPE) is considered positive when an object is above a chosen reference point. However, it can be negative when measured below the reference point. If an object falls below the reference point, the height (h) becomes negative, resulting in a negative GPE. This doesn’t imply a negative energy state but rather a lower potential energy compared to the chosen reference level. The choice of reference point determines the sign convention, and the negative value signifies a lower position in the gravitational field.
