Energy Transformations

Front

What is energy transformation?

Back

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

What is mechanical energy?

Back

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

Front

What is electrical energy?

Back

Electrical energy is the energy caused by the movement of electrons, often used to power devices and appliances.

Front

What is light energy?

Back

Light energy is a form of electromagnetic radiation that is visible to the human eye and is used in various applications, including lighting.

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 does the Law of Conservation of Energy state?

Back

The Law of Conservation of Energy states that energy cannot be created or destroyed, only transformed from one form to another.

Front

Give 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 an example of mechanical energy being transformed into electrical energy?

Back

When a hand generator is turned, mechanical energy is transformed into electrical energy.

Front

How does a hydroelectric dam generate electricity?

Back

A hydroelectric dam converts the potential energy of falling water into mechanical energy, which then turns turbines to generate electrical energy.

Front

What is solar energy?

Back

Solar energy is the energy harnessed from the sun's rays, which can be converted into electrical energy using solar panels.
