Key Vocabulary

media

Energy

Energy is the ability to do work and is required for all activities in our daily lives.

media

Muscular Energy

This energy is stored in our muscles and used for physical tasks like walking and writing.

media

Solar Energy

Solar energy comes from the sun and can be captured by special panels to generate electricity.

media

Fuels

Fuels are substances like petrol or diesel that are burnt to produce energy for various uses.

4

What is Energy?

media
  • Energy is the ability or capacity to do work.

  • It is the power that makes objects move, change, and do things.

  • We use energy for all our daily activities.

5

Multiple Choice

What is the fundamental definition of energy?

1

The ability to do work.

2

The fuel in a car.

3

The heat from fire.

4

The power from electricity.

6

Common Forms of Energy

  • We use muscular energy from our bodies to walk, write, and move things.

  • Electrical energy is used to power our lights, fans, and many other devices.

  • Light energy helps us see, and heat energy is used for cooking food.

  • Sound energy helps us speak, while solar energy from the sun powers homes.

Common Types of Fuels

media

Petrol

  • ​Petrol is a common fuel primarily used for powering smaller vehicles.

  • ​​It is a liquid that releases energy when it is burned.

  • ​This energy powers the engine to make the vehicle move.

media

Diesel

  • ​Diesel is another liquid fuel that is used for larger vehicles.

  • ​​It is commonly used to power trucks, buses, trains, and generators.

  • ​Burning diesel releases the energy needed to move these heavy machines.

media

CNG

  • ​CNG stands for Compressed Natural Gas and is a gaseous fuel.

  • ​​It is used in cars, auto-rickshaws, and buses as a cleaner fuel.

  • ​It burns to release the energy that powers the vehicle's engine.

Multiple Choice

Which of the following correctly describes diesel fuel?

1

Diesel is a gas used mainly in small vehicles like cars

2

Diesel is a liquid fuel used to power large vehicles like trucks, buses, and trains

3

Diesel is a renewable fuel made from plants

4

Diesel releases no energy when burned

10

Common Misconceptions About Energy

Misconception

Correction

Energy is only for major physical activities.

Even studying and thinking require energy.

Solar energy is only useful for providing light.

Solar panels use the sun's energy to generate electricity.

Fuels are exclusively used for vehicles.

Fuels are also used for cooking and running machines.

11

Multiple Choice

How does muscular energy used to kick a ball differ from the solar energy used by a solar-powered calculator?

1

Muscular energy is a type of fuel, but solar energy is not.

2

Muscular energy produces sound, whereas solar energy produces light.

3

There is no real difference; both are used to create motion.

4

Muscular energy comes from our body to create movement, while solar energy is captured from the sun to power devices.

12

Multiple Choice

Why are substances like petrol and diesel classified as 'fuels'?

1

Because they are primarily used to power vehicles.

2

Because they can be burnt to produce useful energy.

3

Because they are liquids that can be poured.

4

Because they are extracted from natural resources.

13

Multiple Choice

How is CNG (Compressed Natural Gas) primarily used?

1

To heat homes and buildings

2

To generate electricity in coal power plants

3

As a fuel for vehicles like cars, buses, and auto-rickshaws

4

As a solid fuel for industrial ovens

14

Multiple Choice

A remote community has abundant sunshine but no access to petrol or the main electricity grid. Based on the concepts learned, what energy sources could they logically use to cook food and light their homes at night?

1

It is impossible for them to have cooking and lighting without petrol.

2

They can use solar panels to generate and store electricity for lighting, and use heat energy from burning wood or other local fuels for cooking.

3

They can use sound energy to generate the power they need.

4

They must rely solely on muscular energy for all tasks.

15

Summary

  • Energy is the fundamental ability required to perform any kind of work.

  • Energy is found in various forms, like muscular, electrical, and light.

  • Fuels release energy when burned to power vehicles and run machines.

  • Solar panels capture solar energy to generate electricity for our homes.
