Angular frequency

Angular frequency is a word we use to describe how fast something is spinning or moving around in circles. Imagine you are spinning a toy top. The toy top spins around in a circle, right?

Now, the speed at which the top is spinning is important, and we can measure it in a special way called angular frequency. It’s like the toy top is doing cartwheels in the air, and we want to count how many cartwheels it does in a certain amount of time.

Angular frequency is usually measured in something called Hertz, which is just a fancy word for “counting how many cartwheels the top does in one second.”

Think of it this way – imagine you’re playing tag with your friends, and you all have to run around in circles around a tree. The faster you run, the more circles you can make in a certain amount of time.

Likewise, when something is spinning really fast, it has a high angular frequency because it is doing lots of “circles” in a short amount of time. When something is spinning slowly, it has a low angular frequency because it is doing fewer “circles” in that same time.
