about the medium of energy?

Question

if we know that energy is being transmitted from one place to another, how can we determine whether the energy is being carried by particles(material bodies) or by wave?

Answer 1

Energy is a relative quality. Objects possess energy depending on point of reference. An object that lies on the table has zero energy with reference to that table. When it comes to the floor however it is a different story. Its energy is
P=mgh
P- potential energy
m - mass
h - hieght of the table.
When this objects fall off the table it will change its potential energy to Kinetic energy (Ke).
Ke=.5 mV^2
V - is the velocity of that object at a particular point of objects fall.

Note that energy is a quantity that is contained within the object and is dependent on the forces this body is subjected to. The energy changes from potential to kinetic as the object moves trough the air.

Now on the molecular level

When this object hits the floor ir molecules and the floor molecules will move generating the heat. Heat is an electromagnetic radiation. By this mechanism the energy possessed by an object is partially converted to an electromagnetic energy.

So energy will be carried by both mass and wave. It the eyes of unified theory the matter and waves are related. So the energy can both be carried by the electromagnetic wave and contained by the objects.

Answer 2

Looking you have what energy in view of.
If any mechanical fluctuations energy is transmitted with particles. If electromagnetic, photons which are both a wave and a particle simultaneously.

Forgive me, I badly know English language.
