Answer 1

Concept:

Mechanical energy is a combination of Kinetic energy and Potential energy.
Mechanical energy is defined as the sum total of kinetic energy and potential energy in an object that is utilized to do work.
Mechanical energy is a form of energy that is related to the position and motion of an object.

Explanation:

From the above explanation, we can see that mechanical energy is combination of kinetic and potential energy

i.e., M.E = K.E + Chemical potential energy

Extra point:

The given table represents a different form of energy

Forms of Energy	Definition
Heat Energy	The heat energy of an object is the overall energy of the molecules that arise due to the motion of the molecules.
Chemical Energy	The Energy produced by breaking or forming chemical bonds between atoms and molecules is called Chemical Energy
Kinetic Energy	Kinetic energy is the energy possessed by virtue of its motion K.E = ½mv² Where m = mass of a body v = velocity of body
Potential Energy	The energy possessed by a body on account of its position or configuration [shape and size] is called potential energy.
