What is Solar Energy?

Back

Solar energy is the energy that comes from the sun's radiation, which can be converted into other forms of energy such as electrical energy.

Front

What is Electrical Energy?

Back

Electrical energy is the energy caused by the movement of electrons through a conductor, often used to power devices.

Describe the energy transformation in a lamp.

Back

The energy transformation in a lamp is electrical energy → thermal energy → light energy.

Front

What is Fission?

Back

Fission is a nuclear reaction in which the nucleus of an atom splits into smaller parts, releasing a large amount of energy.

Front

What is Chemical Energy?

Back

Chemical energy is the energy stored in the bonds of chemical compounds, like food and fuel.

Front

What is Mechanical Energy?

Back

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

Front

What is an example of energy transformation from chemical to electrical to light?

Back

A battery causes a flashlight to shine, transforming chemical energy into electrical energy and then into light energy.

Front

What device transforms electrical energy into mechanical energy and sound?

Back

A pencil sharpener plugged into a wall outlet transforms electrical energy into mechanical energy and sound.

Front

What is the role of a power plant in energy transformation?

Back

A power plant transforms various forms of energy (like nuclear or fossil fuels) into electrical energy for distribution.

Front

What is an example of energy transformation in a candle?

Back

A candle transforms chemical energy from wax into thermal energy and then into light energy.
