5.2.1, 5.2.2, 5.2.3 Energy Transformation

Front

What is energy transformation?

Back

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

Front

What is an example of a device that transforms electrical energy into light energy?

Back

A lightbulb is a device that transforms electrical energy into light energy.

Front

What type of energy transformation occurs in a burning candle?

Back

In a burning candle, chemical energy is transformed into light energy.

Front

What is the law of conservation of energy?

Back

The law of conservation of energy states that energy cannot be created or destroyed, only transformed from one form to another.

Front

Which device transforms electrical energy into mechanical energy?

Back

A fan transforms electrical energy into mechanical energy.

Front

What happens to energy during a chemical reaction?

Back

During a chemical reaction, energy can be transformed from one form to another, such as from chemical energy to thermal energy.

Front

What is an example of energy changing from one form to another?

Back

An example is a toaster, which transforms electrical energy into thermal energy to toast bread.

Front

What type of energy is produced by a battery-powered alarm clock?

Back

An alarm clock powered by a battery transforms electrical energy into sound energy.

Front

What is conduction in terms of energy transfer?

Back

Conduction is the transfer of heat energy through direct contact between materials.

Front

What is an example of energy being conserved?

Back

When a roller coaster goes down a hill, its potential energy is transformed into kinetic energy, but the total energy remains constant.
