ELI5: Explain Like I'm 5

Free space

Free space refers to the areas around us where we can move and play without anything stopping us. Imagine you are in a big room with no furniture or toys. You can walk around, run, jump and do whatever you want without having to worry about bumping into anything. This big room is like free space.

Now imagine if the big room had furniture and toys scattered around. You would have to be careful not to run into anything because if you did, you might get hurt. In this scenario, the space in the room is not completely free.

Similarly, in the real world, free space refers to areas where there are no obstacles or barriers that could prevent you from moving or doing anything you want. This could be a big field, a park, or even your backyard. You can freely move around and play in these spaces without any obstructions.

It is important to have free space because it allows us to move our bodies and be physically active, which is good for our health. It also gives us the opportunity to explore and discover new things. So, always make sure to appreciate and take advantage of free space around you!
