Transformation of Energy

Front

What is heat energy?

Back

Heat energy is a form of energy that is transferred between objects due to a temperature difference. It is often felt as warmth.

Front

Why is it important to conserve energy?

Back

Conserving energy helps reduce harmful pollutants and preserve fossil fuels, ensuring a sustainable environment.

Front

What happens to energy during transformations according to the Law of Conservation of Energy?

Back

Total energy remains constant; energy is neither created nor destroyed.

Front

What is mechanical energy?

Back

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

Front

What is the process of energy transformation when a car brakes?

Back

When a car brakes, mechanical energy is transformed into heat energy due to friction.

Front

How is electrical energy produced in a fossil fuel power plant?

Back

Electrical energy is produced by burning fossil fuels to generate steam that turns turbines.

Front

What is chemical energy?

Back

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

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 heat energy.

Front

What is potential energy?

Back

Potential energy is the stored energy in an object due to its position or state.

Front

What is kinetic energy?

Back

Kinetic energy is the energy of an object in motion, depending on its mass and speed.
