Energy is the capacity for doing work.

Potential energy is energy deriving from position. E.g.: Water in an elevated reservoir has gravitational PE.

A lump of coal or petrol together with oxygen needed for their combustion have chemical energy.

Moving bodies possess kinetic energy (KE).

Other forms of energy are electrical and nuclear, light and sound.

Energy can be converted from one form to another, but the total quantity stays the same according to the law of conservation of energy.

For e.g. As an apple falls, it loses gravitational PE but gains KE.

Although energy is never lost, after a number of conversions, it tends to finish up as the KE of random motion of molecules (of the air for e.g.) at relatively low temperatures.

This

is degraded energy that is difficult to convert to other forms......................

This book has been written for the Medical/Pharmacy/Nursing/ME/M.TECH/BE/B.Tech students of All University with latest syllabus for ECE, EEE, CSE, IT, Mechanical, Bio Medical, Bio Tech, BCA, MCA and All B.Sc Department Students.
