What is machine?

A machine is like a helper that does work for you by using tools and rules.

Imagine you're building a tower with blocks. If you do it all by hand, it might take forever. But if you have a friend who knows exactly how to stack the blocks fast, maybe even using a ramp or a little crane, that’s like having a machine help you out!

A machine has parts that move and work together. Think of your toy car: wheels, axles, and a body. When you push it, the wheels turn, just like how a real machine moves things.

Sometimes, machines use power, just like you need energy to run. A robot vacuum uses electricity, just like you need food to keep going all day!

You see machines everywhere: your fridge cools things down, your bike helps you go faster, and even your toy train is a simple machine that moves on tracks.

So remember, when something does work for you by moving or changing things around, it’s like having a friendly helper, a machine!
