Water has a higher heat capacity compared to a piece of iron, gold, or benzene. This means water can absorb more heat before its temperature rises significantly, making it an effective coolant and thermal buffer.

During the free fall of an object, gravitational potential energy is continually transformed into kinetic energy as the object accelerates towards the ground.
The effect of air resistance is ignored in this analysis to simplify the scenario and focus on the conservation of mechanical energy, where the total mechanical energy remains constant.
As the potential energy decreases during free fall, the kinetic energy increases by an equal amount. This indicates that the decrease in potential energy is converted into kinetic energy.
During the free fall of an object, the potential energy decreases as the height of the object decreases.
