There are two main types of energy: Potential-

energy that is stored and held in readiness

Kinetic- energy in motion when any object is

moving it has kinetic energy

Types

Types of Potential Energy:

1. Gravitational- depends on an object’s height

Example: Sky diving; the greater the altitude you jump from, the greater your gravitational potential energy

Page 6: Chapter 13 Energy Review K. Bollendorf 2009 Table of Contents Slide 1: Title Page Slide 2: Table of Contents Slide 3: Energy Slide 4: Types of Energy.

Types of Potential Energy:

2. Elastic- objects that can be stretched or compressed

Examples: rubber band and a coil spring

Forms of Energy:

1. Mechanical- associated with motion or position of an object

Example: Riding a bike requires mechanical energy.

Forms of Energy:

2. Thermal- associated with an increase in temperature due to the increased movement of molecules within a substance

Example: Grills produce the thermal energy that cooks hamburgers

Forms of Energy:

3. Chemical- stored in chemical bonds

Examples: Stored in the food you eat, wood, or fossil fuels

Forms of Energy:

4. Electrical- energy carried in moving electrical chargers

Examples: Power lines or a car battery

Forms of Energy:

5. Electromagnetic- energy that travels in waves

Examples: Visible light, radio waves, and microwaves

Forms of Energy:

6. Nuclear- energy stored in the nucleus of an atom; When atoms with large nuclei such as uranium are split apart (nuclear fission) tremendous amounts of energy is released

Example: Nuclear power plants heat water to make steam which will be used to make electrical energy

Energy Conversions When energy is converted it changes from one

form of energy into another form of energy. Most forms of energy can be converted into

another form.

Click on the picture below to find out how energy is converted

Page 14: Chapter 13 Energy Review K. Bollendorf 2009 Table of Contents Slide 1: Title Page Slide 2: Table of Contents Slide 3: Energy Slide 4: Types of Energy.

Energy Conversion Examples

1. Light bulbs convert electrical energy into electromagnetic (light) and thermal (heat) energy.

Page 15: Chapter 13 Energy Review K. Bollendorf 2009 Table of Contents Slide 1: Title Page Slide 2: Table of Contents Slide 3: Energy Slide 4: Types of Energy.

Energy Conversion Examples

2. Televisions convert electrical energy into electromagnetic (light) and mechanical (sound) energy.

Page 16: Chapter 13 Energy Review K. Bollendorf 2009 Table of Contents Slide 1: Title Page Slide 2: Table of Contents Slide 3: Energy Slide 4: Types of Energy.

Energy Conversion Examples

2. Trees convert electromagnetic energy into chemical energy through the process of photosynthesis.

Sources of Electrical Energy1. Fossil fuels

Derived from ancient organic material

Includes coal, natural gas, and petroleum

Supported by current infrastructure

Negative impacts: Non-renewable Combustion releases green

house gases such as CO2

Page 18: Chapter 13 Energy Review K. Bollendorf 2009 Table of Contents Slide 1: Title Page Slide 2: Table of Contents Slide 3: Energy Slide 4: Types of Energy.

Sources of Electrical Energy2. Nuclear

Heats water producing steam through controlled nuclear reactions

Steam turns turbines to produce electricity

Produces no atmospheric pollution

Negative impacts: produces radioactive waste Discharges warm water into

nearby rivers affecting aquatic species

Sources of Electrical Energy3. Hydroelectric

Generated from falling water Turns turbines which produce

electricity Produces no pollution Negative impacts: damages

ecosystems through the damming of rivers

4. Wind power Produced from windmills

(called turbines) Produce no pollution Concerns include:

Expensive start-up costs Dependent upon amount of wind Noisy May negatively impact birds
