FORMS OF ENERGY & ENERGY TRANSFORMATION

Front

What is electrical energy?

Back

Electrical energy is the energy of moving electrons, which can be used to power devices and appliances.

Front

What is solar power?

Back

Solar power is energy obtained from the sun's rays, which is a clean and renewable source of energy.

Front

What is the difference between renewable and nonrenewable energy sources?

Back

Renewable energy sources can be replenished naturally (like solar and wind), while nonrenewable sources (like coal and oil) cannot be replaced once used.

Front

What is energy transformation?

Back

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

Front

What type of energy is produced by a moving object?

Back

Kinetic energy is the energy produced by a moving object.

Front

What is mechanical energy?

Back

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

Front

What is 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 an example of energy transformation in a light bulb?

Back

In a light bulb, electrical energy is transformed into light energy and thermal energy.

Front

What is hydroelectric power?

Back

Hydroelectric power is energy generated from the movement of water, typically from rivers or dams.

Front

What is the role of a generator?

Back

A generator converts mechanical energy into electrical energy.
