Question

During the free fall of the object, the decrease in potential energy, at any point in its path, appears as an equal amount of increase in 

(a) kinetic energy

(b) work done

(c) heat energy

(d) gravitational force

Answer 1

Correct option is (a) kinetic energy

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.
