Roundness (object)

Roundness is when an object is shaped like a ball or a circle. Imagine a beach ball - it's round all over, it doesn't have any corners or edges sticking out. That's roundness! Roundness is important because it helps things roll smoothly without any bumps or wobbles. It's also nice to look at - people like things that are nice and round! If you want to check if something is round, you can use a special tool called a roundness tester. It will measure all the different parts of the object and tell you if it's perfectly round or if there are any bumps or dips. Overall, roundness makes things easier to use and more pleasing to the eye!
