The potential energy of a frequency fall...

The potential energy of a frequency falling object decreases progressively. Does this violate the law of conservation of energy? Why.

Text Solution

Verified by Experts

No the process does not violate the law of conservation of energy. This is because when the body falls from a height, then its potential energy changes into kinetic energy progressively. A decrease in the potential energy is equal to an increase in the kinetic energy of the body. During the process, total mechanical energy of the body remains conserved. Therefore the law of conservation of energy is not violated.
