Detailed Solution

The given statement is true.
Kinetic energy:
"Kinetic energy is the energy associated with the movement of objects. Kinetic energy is directly proportional to the mass of the object (

m

) and the square of its velocity (

v

)."

K . E = \frac{1}{2} m v^{2}

Potential energy:
Stored energy that depends upon the relative position of various parts of a system is potential energy.

P . E = mgh

Where

m

is the mass,

g

is the acceleration, and

h

is the height.
“Energy cannot be generated and cannot be destroyed. However, energy can be transformed from one form to another”, is the universal law of conservation of energy. Here, a stone possesses potential energy when it is in the static position at a certain height. However, when it is moving, it possesses kinetic energy, so throwing a stone downwards from a certain height gets the potential energy converted into kinetic energy.
