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.
The total mechanical energy of an object in free fall is the sum of its kinetic energy and potential energy.
Just before the object reaches the ground, the height (h) is zero, so the potential energy is zero. At this point, the velocity (v) is at its maximum, so the kinetic energy is at its highest. The total energy at ...
The sum of the potential energy and kinetic energy of the object remains constant throughout the fall. This is because the total mechanical energy (potential energy + kinetic energy) is conserved in the absence of air resistance and other external ...
The kinetic energy (KE) of the object at a given instant when its velocity is v is given by 1/2mv². This represents the energy due to the object’s motion.
The total energy of the object at the height h is its potential energy, which is mgh. At this point, the kinetic energy is zero, so the total energy is entirely due to its potential energy.
The kinetic energy is zero at the start because the object is initially at rest. Since kinetic energy is given by 1/2 mv², and the initial velocity (v) is zero, the kinetic energy is also zero.
