What is Frames per second (fps)?

Frames per second (fps) is how many pictures are shown every second to make a smooth moving picture.

Imagine you're watching your favorite cartoon on TV. Each frame is like one still picture in the cartoon, kind of like when you flip through the pages of a comic book really fast, and it looks like the characters are moving. Now, if the cartoon shows 10 frames every second, that means it's showing 10 different pictures each second.

If the cartoon only shows 5 frames per second, you might see the characters jumping or turning slowly, kind of like when you flip through a comic book very slowly. But if it shows 30 frames per second, everything moves smoothly, just like real life!

So, frames per second is like the speed at which pictures are shown to make things move on screen, more frames mean smoother motion, and fewer frames can look a little choppy.
