The potential energy of a freely falling object decreases progressively. Does this violate the law of conservation of energy? Why?
ScienceClass 9CBSEAnswered 27 Mar 2026
Answer
Solution:
No, the method doesn’t violate the law of conservation of energy. This is because when the body falls from a height, 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. Throughout the method, the total mechanical energy of the body remains conserved. Therefore, the law of conservation of energy isn’t desecrated.
