What is energy transformation?

Back

Energy transformation is the process of changing energy from one form to another, such as converting chemical energy in food into mechanical energy for movement.

Front

What are the main types of energy?

Back

The main types of energy include mechanical, thermal, chemical, electrical, radiant (light), and sound energy.

Front

What energy transformation occurs when rubbing hands together?

Back

Chemical energy from food is transformed into mechanical energy (movement) and then into thermal energy (heat) due to friction.

Front

What type of energy does a battery store?

Back

A battery stores chemical energy.

Front

What energy transformation occurs in a pencil sharpener?

Back

Electrical energy is transformed into mechanical energy (for the motor) and then into sound energy (the noise it makes).

Front

What types of energy does a television transform electrical energy into?

Back

A television transforms electrical energy into light, thermal (heat), and sound energy.

Front

What is an example of energy transformation in a lamp?

Back

When a lamp is turned on, electrical energy is transformed into light energy and thermal energy (heat).

Front

Which energy form is NOT produced by a lamp?

Back

Chemical energy is NOT produced by a lamp.

Front

What is mechanical energy?

Back

Mechanical energy is the energy associated with the motion and position of an object.

Front

What is thermal energy?

Back

Thermal energy is the energy that comes from the temperature of matter, often felt as heat.
