Heat energyA form of kinetic energy that flows from one body to another of different temperature.

Mechanical EnergyEnergy produced fro machines set in motion.

Chemical EnergyForm of Energy that can be found in fireworks, food and medicines.

Electrical Energy

Can be produced when the energy of a material flow together.

Sound EnergySound energy travels in waves.

Radiant EnergyComes from all glowing heat source and radiates in all directions therefore sun is the chief source of radiant energy.

Nuclear EnergyComes from either splitting or combining particles found in the nucleus.

Geothermal Energy

Thermal energy is the part of the total, internal energy of a thermodynamic system or sample of matter that results in the system's temperature.

Forms of Energy

How it is Formed

How it is Used

Heat By rubbing two faces together

For cooking foodFor pressing clothes

Mechanical By using machines,moving objects

For running motor vehicles

Chemical By releasing stored energy in substances

For making processed food and medicines

Electrical By the flow of electrons

For supplying power to electric bulbs and appliances

Sound By vibrating bodies/objects

For providing music and communication

Radiant By waves moving through space

For drying clothes for illumination

Nuclear By separating or combining atomic particles

For generating electricity

Geothermal By harnessing steam from the underground

For generating electricity

POINTS TO PONDER Chemical, sound, thermal, mechanical, radiant, nuclear, and

electrical are forms of energy.

Chemical energy is stored in substances.

Mechanical energy is found in moving bodies such as wheels, windmills, and running water.

Nuclear energy can be both helpful or harmful to man.

Radiant energy is used to dry our clothes, disinfect our beddings, or diagnose diseases.
