TYPES OF ENERGY Mechanical, Thermal, Electrical, Chemical, Nuclear, and Electromagnetic,
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 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.
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 stored within the molecules of a substance and available for release through chemical reactions. The chemical bonds store energy that is transformed when these bonds are broken or changed CHEMICAL CHANGE
8
Examples of Chemical Energy
9
What is Nuclear Energy? -Energy stored in the nucleus in an atom. -Two types of ways to harness the potential energy in the nucleus of the atom FISSION SPLITTING of nucleus FUSION When the nuclei of atoms FUSE These reactions occur constantly on the SUN Utilized in NUCLEAR POWER PLANTS
10
What is Electromagnetic Energy? o Light energy o Includes energy from gamma rays, xrays, ultraviolet rays, visible light, infrared rays, microwave and radio bands
11
Law of the Conservation of Energy Energy can neither be created nor destroyed, it only CHANGES FORMS. Energy transforms from one type to another, but is conserved and passed along!!
12
QUIZ TIME! What type of energy cooks food in a microwave oven? ELECTROMAGNETIC ENERGY What type of energy is the spinning plate inside of a microwave oven? MECHANICAL ENERGY
13
QUIZ TIME! Electrical energy is transported to your house through power lines. When you plug an electric fan to a power outlet, electrical energy is transformed into what type of energy? MECHANICAL ENERGY
14
QUIZ TIME! What energy transformation occurs when an electric lamp is turned on? ELECTRICAL ENERGY ELECTROMAGNETIC ENERGY
15
What types of energy are shown below? Mechanical and Thermal Energy (Don’t forget friction)
16
What type of energy is shown below? Chemical Energy
17
What types of energy are shown below? Electrical, Mechanical and Electromagnetic Energy
18
What type of energy is shown below? Chemical Energy (yummy)
19
What type of energy is shown below? Electrical & Thermal Energy
20
Draw a flow map showing the flow of energy transformations in a car from starting vehicle to driving. You should have 5 different types of energy.
21
Energy Transfer Chemical Electrical Sound (mechanical) Light (Electromagnetic) Thermal Mechanical
