Understanding Energy Conversion: Forms, Transformations, and Applications

Energy can be found in a number of different forms. It can be chemical energy, electricalenergy, heat (thermal energy), light (radiantenergy), mechanical energy (kinetic energy), and nuclear energy. The Law of Conservation of Energy Energy is converted from one form to another, but it is never created or destroyed.

Energy transformation is the change in energy form. Nuclear energy is converted to mechanical energy and then into electrical energy in a nuclear power plant. Gasoline, chemical energy, is converted to heat energy & mechanical energy by a car.

Mechanical energy is converted into thermal energy when you bounce a ball Before bouncing After bouncing

Solar Cell Chemical Energy  Heat & light energy What kind of energy transformations are shown in the following pictures? Solar energy (light energy)  Chemical Energy Chemical energy  Mechanical Energy Wind energy  Mechanical Energy Solar energy (light energy)  Electrical Energy

Which of the following can be used to transform chemical energy into heat energy? A. A windmill turning Answer: B B. lighting a match C. solar panels D. a light bulb

Presentation Transcript

Energy can change from one form to another without a net loss or gain.

One form of energy can be converted into another form of energy. Conservative and non-conservative forces CONSERVATION

One form of energy can be converted into another form of energy. Conservation of energy Conservative and non-cons

Energy can change from one form to another without a net loss or gain.

But is it ethical?

...But is it Scientific?

External signal is received and converted to another form to elicit a response

This is another one

REMEMBER: Energy cannot be created or destroyed – This is the Law of Conservation of Energy.

Energy can change from one form to another without a net loss or gain.

One form of energy can be converted into another form of energy. Conservation of energy

Energy can be transformed from one form to another

Energy Transformation- when energy is changed from one form to another

Venir is another irregular verb, but it is conjugated very similarly to Tener

Energy can change from one form to another without a net loss or gain.

Energy can be transformed from one form to another

During chemical changes matter cannot be created or destroyed. It is merely rearranged. Example

Energy can change from one form to another without a net loss or gain.

It Is What It Is…Or Is It?

Scent Marketing is it Manipulative or is it Just Another Clever Marketing Technique

KEY TERMS An energy transformation occurs when energy changes from one form to another.

(1) Energy transformation = energy changing from one form to another Conversion = transformation
