Power is defined as the rate of doing work or the rate of transfer of energy.

The fundamental concept used to measure the speed of work done by machines is power.

This transformation results in a continual increase in the object’s velocity as it falls, with its potential energy decreasing while its kinetic energy increases, maintaining the total mechanical energy constant.

In this scenario, air resistance is ignored, allowing for a continual transformation of gravitational potential energy into kinetic energy without any loss due to air resistance.

The decrease in potential energy of the object as it falls is exactly balanced by an equal increase in kinetic energy, maintaining the total mechanical energy constant.
