If air resistance is negligible, the sum total of potential and kineti...
The sum total of potential and kinetic energies of a freely falling body remains the same if air resistance is negligible. This is known as the law of conservation of energy.
Explanation:
Potential energy is the energy possessed by an object due to its position or height above the ground. When an object is lifted to a certain height, it gains potential energy. Kinetic energy is the energy possessed by an object due to its motion. When an object is in motion, it gains kinetic energy.
When a body is freely falling, it loses potential energy as it moves down due to gravity. At the same time, it gains kinetic energy as its velocity increases. The sum total of potential and kinetic energies of the body remains the same, as the loss of potential energy is equal to the gain in kinetic energy.
This is because energy cannot be created or destroyed, only transferred from one form to another. In the case of a freely falling body, the potential energy is converted into kinetic energy. The total energy of the body remains constant throughout its fall.
The law of conservation of energy is an important principle in physics and is applicable to many different situations. It helps us understand how energy is transferred and transformed in various processes.
