Detailed Solution

A bag of wheat is dropped from a height

h

. Here the potential energy is converted into kinetic energy in this process.
Mechanical Energy is the term used for the sum of the kinetic and potential energy of a body. An object’s mechanical energy can result from its motion ( i.e., kinetic energy) and its stored energy of position (i.e., potential energy).
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 to the square of its velocity (

v

).”

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

Potential energy:
“Potential energy is the energy that is stored in an object due to its position or configuration.”

P . E = mgh

Where

m

is the mass,

g

is the acceleration, and

h

is the height.
A bag of wheat at a height has potential energy. When it is dropped, its potential energy gets converted into kinetic energy and its speed increases as it falls under the influence of acceleration due to gravity. At the point it reaches the ground, all the potential energy gets converted into kinetic energy.
