# TYPES OF ENERGY - Boyertown Area School District Identify all the forms of energy you see in the picture below. Learning Objectives I can describe the 6 forms of energy. I can give example of the 6 forms of energy. In our previous lesson, we learned that there are two

types of energy: Potential Energy & Kinetic Energy There are also many forms of energy. This lesson will provide an overview of some forms of energy. Forms of Energy Thermal energy (Heat)

Mechanical energy (includes sound energy) Electromagnetic (light/radiant) energy Electrical energy Chemical energy Nuclear energy

Use Your Graphic Organizer to Record Important Information Thermal Energy (Heat) The total potential and kinetic energy related to all the motion of the particles in an object. Energy that is created in the movement of particles (atoms) that produces heat. Thermal (Heat) energy increases as temperature

increases The faster the particles (atoms) move, the greater the kinetic energy and the greater the objects thermal energy. The opposite is also true. Thermal energy also depends on the number of particles. If there are more particles, there is more thermal energy. Thermal (Heat) Energy

A hot object is one whose atoms and molecules are excited and show rapid movement. (More heat energy) A cooler object's molecules and atoms will show

less movement. Which has more thermal energy? Why? Hot Chocolate Ice Water

Mechanical Energy Energy of motion The total energy of motion and position of an object (potential energy + kinetic energy) Law of Conservation of Energy KE + PE (beginning) = KE + PE (end) Mechanical energy can be all

potential energy, all kinetic energy, or some of each. Mechanical Energy The mechanical energy of an object stays the same, but the potential and kinetic energy of an object can increase or decrease.

Think of juggling. The kinetic energy decreases until all of the balls kinetic energy turns into potential energy, and it stops moving upward. As the ball falls back down again, its potential energy starts changing back into kinetic energy. Sound Energy a form of Mechanical Sound energy is caused by an objects vibrations

A vibrating object transmits energy through the air around it in waves (longitudinal waves) Examples of Mechanical Energy Electromagnetic (Light/Radiant) Energy Energy created by vibrating particles

that create waves that travel through space and time. [These waves are called electromagnetic waves.] Electromagnetic energy can be absorbed, transmitted, or reflected. Includes energy from gamma rays, xrays, ultraviolet rays, visible light, infrared rays, microwave and radio bands. (Electromagnetic spectrum)

Examples of Electromagnetic Energy Electrical Energy Energy that is associated with electric charges. Energy that is carried by an electrical current (the movement of electrons, the negatively charged

particles of atoms.) The electrical energy used in your home can be thought of as potential energy that is used when you plug in an electrical appliance and use it. Chemical Energy

Energy stored in chemical bonds When chemical bonds are broken, new chemicals are formed and some of it is released energy Examples: Food, Battery, Burning candle

or Wood, Fireworks, Fossil Fuels, Gasoline Examples of Chemical Energy Nuclear Energy The energy stored in atomic nuclei

Energy released from splitting atoms (fission) or process of making a single heavy nucleus from 2 lighter ones (Fusion) Examples: Nuclear fusion and nuclear

fission. 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 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 What type of energy is shown below? Chemical Energy
