Poundal

Imagine you have a toy car and you want to push it. The poundal is a measurement that tells you how strong you need to push to make the car move. It's like a special ruler that measures how fast you can make something go by pushing it.

The poundal is kind of like the pound, but instead of measuring weight, like how heavy something is, it measures force, which is how hard you push or pull something. The poundal is used to measure the force needed to move something that weighs one pound.

So, if you have a toy car that weighs one pound, and you push it with one poundal of force, it will start to move. And the faster you can push it with one poundal, the faster it will go.

But poundals are not really used much anymore. Nowadays, people mostly use another unit called the newton to measure force. But understanding the poundal can help you understand the concept of force and how much push or pull is needed to make something move.
