👉 A circular device capable of rotating on its axis, facilitating movement or transportation or performing labour in machines.
Alright class, settle down and let’s take a look! That dictionary definition is quite thorough, isn't it? Let's break it down nice and slow. Essentially, when we say "wheel," we’re talking about something that rotates – it spins around and around! Think of a merry-go-round, or a spinning top, that's the key to its core. The dictionary says it “facilitates movement or transportation,” which means it helps us get from one place to another. Like a bicycle wheel, a car wheel, or even a wagon wheel – they all let us roll along! And you’re right, it can also "perform labour in machines.” Think of a potter's wheel - it spins and helps the artist shape clay. It does work! So, to put it simply: A wheel is a round thing that turns, making things move or helping machines do their job. Does that make sense? Any questions about this circular friend we call a 'wheel'?
