What is energy transformation?

Back

Energy transformation is the process of changing energy from one form to another, such as converting electrical energy into mechanical energy.

Front

List the forms of energy involved in the transformation from electrical energy to mechanical energy.

Back

Electrical energy is transformed into mechanical energy, sound energy, and thermal energy.

Front

What type of energy does a battery produce?

Back

A battery produces electrical energy.

Front

What is the primary form of energy produced in electrical to thermal energy conversion?

Back

The primary form of energy produced is thermal energy.

Front

What energy conversion occurs when gasoline is used in a car?

Back

The energy conversion is from chemical energy to mechanical energy.

Front

Define thermal energy.

Back

Thermal energy is the energy that comes from the temperature of matter, which is the total kinetic energy of particles in an object.

Front

What is mechanical energy?

Back

Mechanical energy is the sum of potential energy and kinetic energy in an object, which is used to do work.

Front

Explain the difference between potential energy and kinetic energy.

Back

Potential energy is stored energy based on an object's position, while kinetic energy is the energy of an object in motion.

Front

What is sound energy?

Back

Sound energy is a form of energy produced by vibrating sound waves.

Front

What is chemical energy?

Back

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