Energy Transformation Study Guide

Front

What are the energy transformations that occur when a battery powers a phone that produces sound?

Back

Chemical energy in the battery is transformed into electrical energy, which is then transformed into sound (mechanical) energy when the phone chimes.

Front

What type of energy is associated with light and is emitted by sources like the sun?

Back

Radiant energy.

Front

Which of the following is not a form of energy: kinetic, potential, friction, or thermal?

Back

Friction is not a form of energy.

Front

What type of energy transformation occurs when solar power is converted into electricity?

Back

Radiant energy is transformed into electrical energy.

Front

What form of energy does a radio convert electrical energy into?

Back

Sound (mechanical) energy.

Front

Define chemical energy.

Back

Chemical energy is the energy stored in the bonds of chemical compounds, like atoms and molecules.

Front

What is electrical energy?

Back

Electrical energy is the energy caused by the movement of electrons.

Front

Explain the concept of mechanical energy.

Back

Mechanical energy is the sum of potential energy and kinetic energy in an object.

Front

What is the difference between kinetic and potential energy?

Back

Kinetic energy is the energy of motion, while potential energy is stored energy based on an object's position.

Front

What is radiant energy and where can it be found?

Back

Radiant energy is energy carried by electromagnetic waves, such as light from the sun.
