Energy Transformation

Front

What is energy transformation?

Back

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

Front

What are the main types of energy?

Back

The main types of energy include chemical, electrical, mechanical, thermal, and light energy.

Front

Describe the energy transformation in a flashlight.

Back

When a flashlight is turned on, the energy transformation occurs as follows: chemical energy (from batteries) → electrical energy → light energy.

Front

What energy transformation occurs when water falls through a dam?

Back

The energy transformation is: mechanical energy (from falling water) → electrical energy (produced by a generator) → light energy (used in homes and offices).

Front

Give an example of light energy being transformed into chemical energy.

Back

A plant makes sugar in the sunlight through the process of photosynthesis.

Front

What happens to energy when a candle burns?

Back

When a candle burns, chemical energy is transformed into light energy.

Front

What is photosynthesis?

Back

Photosynthesis is the process by which green plants use sunlight to convert carbon dioxide and water into glucose (chemical energy) and oxygen.

Front

What is the role of a turbine in energy transformation?

Back

A turbine converts mechanical energy (from moving water or wind) into electrical energy.

Front

How does a battery work in terms of energy transformation?

Back

A battery transforms chemical energy into electrical energy to power devices.

Front

What is an example of mechanical energy being transformed into electrical energy?

Back

When a wind turbine spins, it transforms mechanical energy from the wind into electrical energy.
