how is energy tranferred when one object dose work on another?

Question

sciense question

Answer 1

There are only two ways of energy transfer; one as result of temperature difference and other where temperature difference is not involved. In the later we may be able to visualize it as work done by some force or we may not be able to do so. But with our pre-decided conception of energy we find that energy of one object gets reduced and the other gets increased then we say that the object/system whose energy is reduced has done work upon the object which has gained energy. The concept of energy is related to work on one hand and force on the other.

Answer 2

. When one object does work on another, energy may be transferred as kinetic energy (motion), radiant energy (heat or, in more rare cases, visible light or maybe even ultraviolet light) or a change in potential energy (becoming placed higher in a gravitational field for example).
. When a pump pumps water, it does work on the water causing it to move with momentum and kinetic energy, but it also heats it. In industry, it is sometimes necessary to conduct high temperature tests on a boiler before it is ready to be fueled up. In those cases, the plant owners can sometimes boil the water in the boiler just by pumping it in a circle as hard as they can.

Answer 3

When the objects make contact, the electrons from each object, at the contact point, exert an electromagnetic force, repelling the electrons of the other. The effects of the force inversely change the kinetic energy of each object.
