ELI5 When a car is moving on TV or a movie the wheels look like they're moving backwards...

If you take a picture of a clock every minute, then show the pictures in rapid succession, it will go from 12:00 to 12:01 to 12:02... and it'll look like it's going forward.

If you take a picture of a clock every 23 hours and 59 minutes, then show the pictures in rapid succession, it will go from 12:00 to 11:59 to 11:58... and it'll look like it's going backwards.

Motion picture cameras take pictures much faster than once a minute, but the same thing can apply. If the wheel is spinning at a speed where it rotates 90% of the way between frames, it will look like it's spinning backwards.
