ENERGY
ability to do work is called energy
energy cause
work to be done
WORK
work is the product of force and distance through which force acts
when force cause displacement in its own direction, work is said to be done
WORK = FORCE x DISPLACEMENT
in SI system the unit of work is
joule
1J = 1N x 1m
various forms of ENERGY
mechanical energy
Heat energy
light energy
sound energy
electric energy
magnetic energy
chemical energy
nuclear energy
inter-conversion of ENERGY
mechanical energy into heat energy
mechanical energy into light energy
mechanical energy into sound energy
mechanical energy into potential energy
mechanical energy into kinetic energy
potential energy into electric energy
chemical energy into light energy
electric energy into heat energy
heat energy into electric energy
electric energy into magnetic energy
electric energy into light energy
light energy into electric energy
sound energy into electric energy
electric energy into sound energy
chemical energy into mechanical energy
electric energy into chemical energy
light energy into chemical energy
law of conservation of ENERGY
ENERGY CANNOT BE CREATED OR DESTROYED BUT IT CAN ONLY CHANGE FROM 1 FOR TO ANOTHER
SUN THE ULTIMATE SOURCE OF ENERGY
yes as all energy chains start from the sum
