Dimensionless quantity
Hi there! A dimensionless quantity is like a special toy that doesn't have any size or measurement. You know how when you play with your legos, you can count how many blocks you have, and you can even measure the length and width of your creations? Well, a dimensionless quantity doesn't have any blocks or measurements.
Instead, it's like a toy that tells you something important about the other toys you're playing with. For example, imagine you have a toy car and a toy train. You can count how many wheels each toy has, but that doesn't really tell you which one is faster. But if you measure how far each toy can go in the same amount of time, you could compare them and say which one is faster.
A dimensionless quantity is like that - it helps you compare things without worrying about their size or units. It's like a toy that tells you how much of something you have, but without measuring it in inches or pounds or other units. Does that make sense to you?
