2. TYPES OF ENERGY Mechanical, Electromagnetic, Electrical, Chemical, Thermal, & Nuclear

3. What is Mechanical Energy? o Energy due to a object’s motion (kinetic) or position (potential). The bowling ball has mechanical energy. When the ball strikes the pins, mechanical energy is transferred to the pins!

4. Examples of Mechanical Energy

5. What is Electromagnetic Energy? o Light energy o Includes energy from gamma rays, xrays, ultraviolet rays, visible light, infrared rays, microwave and radio bands

6. What is Electrical Energy? o Energy caused by the movement of electrons o Easily transported through power lines and converted into other forms of energy

7. What is Chemical Energy? o Energy that is available for release from chemical reactions. The chemical bonds in a matchstick store energy that is transformed into thermal energy when the match is struck.

8. Examples of Chemical Energy

9. What is Thermal Energy? o Heat energy o The heat energy of an object determines how active its atoms are. A hot object is one whose atoms and molecules are excited and show rapid movement. A cooler object's molecules and atoms will show less movement.

10. What is Nuclear Energy? o Energy stored in the nuclei of atoms o Releasing this energy by splitting atoms is called FISSION oReleasing this energy when less massive nuclei merge to form a more massive nucleus is FUSION

74. Heat Energy

75. Conduction Heat transfer by direct contact of particles is called conduction. When your hands touches a metal spoon sitting in a boiling pot of soup, the heat from the bottom of the pot is transferred to you hand by conduction.

76. Conduction

77. Convection Convection is the transfer of heat by the movement of a heated fluid. Convection deals with density. Density is the measure of how much mass is there in a volume of a substance.

78. Convection When a liquid or gas is heated, the particles move faster and the density decreases. As the fluid becomes cooler, its density increases. As density increases, the fluid sinks. Heat Rises!!

79. Convection The heating and cooling of the fluid, changes in the fluid’s density, and the force of gravity combine to set convection currents in motion. Without heat, convection currents will eventually come to a stop.

80. Convection in the Earth’s Mantle The heat source for these convection currents in the mantle comes from the heat of the Earth’s core.

81. Radiation Radiation is the transfer of energy through empty space. Heat transfer by radiation takes place with no direct contact between a heat source and an object.

82. Heat from the Sun Energy is constantly on the move! The movement of energy from warmer object to a cooler object is called a heat transfer There are three types of heat transfer: radiation, conduction, and convection.
