Educational worksheet on forms of energy featuring matching exercises and image-based identification for children.

Task 1: Join the form of energy with their definitions.

We need to match each form of energy with its correct definition. Let's go through them one by one:

#### Definitions:
1. The energy that is contained in food.
- This is Chemical energy because food contains chemical bonds that store energy, which can be released during digestion or combustion.

2. This type of energy is created by waves of sound.
- This is Sound energy because sound travels as waves and carries energy.

3. When an object is elevated it has this type of energy.
- This is Potential energy because when an object is raised, it gains gravitational potential energy due to its position.

4. The energy we use to power our TVs.
- This is Electrical energy because TVs run on electricity.

5. The sum of kinetic and potential energy.
- This is Mechanical energy because mechanical energy is the total of an object's kinetic and potential energy.

6. The energy of heat.
- This is Thermal energy because heat is a form of thermal energy.

7. Movement creates this type of energy.
- This is Kinetic energy because kinetic energy is the energy of motion.

8. The energy produced by light sources.
- This is Light energy because light sources emit photons, which carry light energy.

#### Matched Pairs:
1. Sound energy → This type of energy is created by waves of sound.
2. Kinetic energy → Movement creates this type of energy.
3. Thermal energy → The energy of heat.
4. Light energy → The energy produced by light sources.
5. Potential energy → When an object is elevated it has this type of energy.
6. Mechanical energy → The sum of kinetic and potential energy.
7. Chemical energy → The energy that is contained in food.
8. Electrical energy → The energy we use to power our TVs.

Task 2: Write the type of energy below each picture.

Now, let's identify the type of energy depicted in each image.

#### Image 1: A car racing on a track.
- Energy: The car is moving, so it has Kinetic energy.

#### Image 2: An apple falling from a tree.
- Energy: The apple has the potential to fall due to gravity, so it has Potential energy before it falls. Once it starts falling, it also has Kinetic energy. However, since the apple is shown suspended, the primary energy here is Potential energy.

#### Image 3: A glowing light bulb.
- Energy: The light bulb emits light, so it has Light energy.

#### Image 4: A person eating food.
- Energy: The food contains energy that will be used by the body, so it has Chemical energy.

#### Image 5: A person playing a saxophone.
- Energy: Playing a saxophone produces sound, so it involves Sound energy.

#### Image 6: A roller coaster at the top of a hill.
- Energy: The roller coaster is elevated, so it has Potential energy.
