Humans use energy in different ways to get things done every day. This shows us how energy and work go hand in hand. Let’s look at some examples!

1. Physical Energy

When we do things like walking, lifting, or running, our bodies turn food into energy. This is called biochemical energy. Here’s how it works:

• Walking: When you walk, your body uses energy from the food you eat. It’s like charging a battery!

2. Household Machines

We depend on machines that use different types of energy. Here are a few common ones:

• Refrigerators: These use electrical energy to keep our food fresh. They work by taking heat out from inside the fridge and pushing it outside.
• Washing Machines: They change electrical energy into mechanical energy to wash clothes by moving them around.

3. Transportation

Energy is very important when we travel:

• Cars: Cars turn chemical energy from fuel into mechanical energy to drive. For example, when you drive to school, your car burns fuel to make energy so it can go.
• Public Transportation: Buses and trains use electrical or diesel energy. They are made to carry a lot of people, which helps save energy when we share rides.

4. Everyday Appliances

Many of our daily tasks use energy to make life easier:

• Microwaves: These turn electrical energy into waves that heat our food quickly.
• Vacuum Cleaners: They use electrical energy to create suction, making cleaning easier and saving us time.

In short, energy is a big part of our lives. It changes forms to help us with daily tasks, from walking to using different machines. By learning about how energy works, we can see how it makes our daily lives better!
