list four activities that require a great deal of energy
radiation
Sound is a form of energy that is produced when objects vibrate and create compression waves through a medium like air. Sound energy can be heard and has the ability to travel through different mediums, but it is not considered matter itself.

For example thermal energy.
The only kind of energy that dark matter is -- well, MATTER. Or mass, if you prefer, which is the same thing. We don't know what KIND of matter this stuff is, hence the name "dark." The only two things we know about dark matter is that (1) it interacts with baryonic matter via gravity but (2) it does NOT interact with baryonic matter via the electromagnetic force or the strong force. At this point, we're still working on what type of matter would do that.

it has kinetic energy = 1/2 mass x velocity squared
During burning, one kind of matter turns into its ash, gases, and heat energy. The chemical bonds in the matter are broken, releasing energy in the form of heat and light, and leaving behind the remains in the form of ash.
Thermal energy is the form of energy that measures temperature. It is the energy that comes from the motion of particles in matter, which determines the temperature of an object or substance.
Because energy can't be created (or destroyed, for that matter); it can only be transformed from one form into another. Note that we're taking the relativistic definition of "energy" here in which matter is really a kind of frozen energy.
It is not a matter. It is one of seven kind of energy. Electricity is produce generator.
