As the object falls, its kinetic energy increases because its velocity increases due to the conversion of potential energy into kinetic energy.

As the object falls, its potential energy decreases because it loses height relative to the reference point.

At the beginning of its fall, the total energy of the object is equal to its potential energy, which is mgh.

The kinetic energy is zero initially because the object’s velocity is zero at the start of its fall.

It provides a fundamental principle in physics, ensuring that energy is conserved and allowing for predictions and analysis of various physical processes, from simple mechanical systems to complex chemical reactions and nuclear processes.
