• Gravitational

• Elastic

• Chemical

• Nuclear

• Sound

Multiple Select

• Thermal (heat)

• Electrical

• Radiant (Light)

• Sound

Multiple Choice

Multiple Choice

The turkey is being cooked in the oven by _____ Energy.

• Thermal

• Solar

• Electrical

• None

Multiple Choice

What form of energy is this?

• Electrical

• Mechanical

• Chemical

• Thermal

Multiple Choice

Which is an example of electrical energy?

You also learned the "Law of Conservation of Energy"

​

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

Terminology to Remember

Converted / Transformed / Transferred

These three words ALL mean to change. They have the SAME definition.

​

Estas tres palabras TODAS significan cambiar. Tienen la MISMA definición.

​

Conversión / Transformación / Transferencia

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.

​

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

Let's Practice!

Multiple Choice

A battery converts what type of energy to another?

• sound to kinetic
• light to heat
• mechanical to electrical
• chemical to electrical

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

• Radiant (Light) Energy

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

​

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

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

• Electrical

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.***
