Energy Transformation

Energy Transformations

Answer each question and fill in your notes in schoology.

Yesterday you learned "2 Types and 4 Forms of Energy"

• Types: Potential Energy and Kinetic Energy

• Forms of Energy: Thermal, Electrical, Mechanical, and Radiant

• Extra Forms of Energy You Saw: Sound, Chemical, Nuclear, Elastic Potential Energy and Gravitational Potential.

You also learned the "Law of Conservation of Energy"

***Energy cannot be destroyed, but it can be transformed.***

Today we will look at how energy can change from one form to another.

Energy changing from one form to another...

is sometimes called energy conversion or energy transformation.

>>> Any form of energy can change into any other form of energy.

Multiple Choice

See the picture. There is electrical energy coming from the outlet in the wall. When the energy goes into the lamp what energy does it transform into?

• Mechanical Energy

• Thermal Energy

• Sound Energy

• Light Energy

Often one form of energy can change into more than one form.

Chemical-> Heat-> Kinetic-> Electrical-> Heat

Multiple Select

When wood burn it changes from chemical energy to what 2 other forms of energy? Click the 2 other forms.

• Radiant (Light)

• Nuclear

• Heat

• Mechanical

Multiple Select

A gasoline-powered generator is used to provide lighting for a house.

Choose the best 3 energy forms found in this transformation example?

• Chemical

• Mechanical

• Light

• Nuclear

Multiple Choice

Skateboarder #1 is showing potential energy as he waits at the top of the half pipe.

Skateboarder #2 has dropped into the half pipe, to what type of energy has he converted his potential energy?

• Potential

• Thermal

• Kinetic

• Chemical

Food is chemical energy used to make the body function.

• It is converted into kinetic energy to help the body move

• It is also converted into thermal energy to keep the body warm.

Energy Conversion in Plants

• Chemical energy stored in the food we eat ultimately comes from the sun.

• The process is called photosynthesis. Light energy is converted into chemical energy.

Energy Conversions are needed in EVERYTHING we do.

(Think of what you do everyday.)

REMEMBER: Any form of energy can change into any other form of energy.

***Energy cannot be destroyed, but it can be transformed.***
