Geothermal Energy
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.
