Energy Section 14.6 Forms of Energy Forms of Energy The six major forms of energy are:

1. 2. 3. 4. 5. 6. Mechanical Energy

Thermal Energy Chemical Energy Electrical Energy Electromagnetic Energy Nuclear Energy Mechanical Energy

Mechanical Energy Energy associated with the motion and position of everyday objects. Examples 1. Speeding Train 2. Bouncing balls 3. Sprinting Athletes

Thermal Energy Thermal Energy Total potential and kinetic energy all the microscopic particles in an object Examples 1. Friction 2. Boiling Water

3. Heating Pad Chemical Energy Chemical Energy Energy stored in the chemical bonds in compounds. When these bonds are broken, the released energy can do work. Examples

1. Fireworks 2. Burning Wood 3. Gasoline Electrical Energy Electrical Energy Energy associated with electrical charges.

Examples 1. Lightning Bolts 2. Television 3. Toaster Electromagnetic Energy Electromagnetic Energy

Energy that travels though space in the form of waves. Examples 1. Visible Light 2. X-Rays 3. Tanning Beds (UV Light) Nuclear Energy

Nuclear Energy Energy stored in atomic nuclei Examples 1. Nuclear Power Plant (Reactor) 2. Sun 3. Nuclear Weapons Energy Conversion

Energy Conversion Energy can be converted from one form to another Wind-Up Toy Elastic Potential Energy in a compressed spring. When the spindle unwinds, potential energy is converted to kinetic energy of the toys moving parts.

Energy Conservation Energy Conservation The Law of conservation of energy states that energy can not be created or destroyed, it only changes form. Bicycle The bicycle had kinetic energy. The bike slowed down and stopped because of frictional forces acting over a distance. The

work done by friction changes the kinetic energy into thermal energy. So when we account for the thermal energy (friction) this is equal to the kinetic energy the bike previously had, thus energy is conserved overall. Roller Coaster Energy Conversion / Energy Conservation

Energy Gravitational Potential Energy if an object is converted to: Energy How is potential energy converted to kinetic energy in the following pendulum:

Energy How is potential energy converted to kinetic energy in the following pendulum: Energy Where is the greatest PE and KE points on the following pendulum?

Activity Label the types of energy in each example: Cars engines gears: Mechanical Energy Gasoline: Chemical Energy Friction in the engine creating heat: Thermal Energy The car battery Chemical Energy

Activity As a group, find the five steps (four types of energy) that a match uses to convert energy 1. Muscles us chemical energy to move your hand (kinetic energy) to strike the match 2. Friction between the match and the matchbox converts kinetic energy into thermal energy (heat).

3. Thermal energy to chemical energy to light the match 4. Chemical energy converted to thermal energy 5. Thermal energy to electromagnetic energy (Flame Waves)
