This is a simple website but a fun way to learn about how gears work. Start by using your mouse to create a circle of any size. It will automatically turn into gear. Then draw another circle next to it – again creating another gear. Draw gears coming off gears if you like! Then extend the red arrow around the gear – the longer you make it the faster the gear goes. A shorter arrow will mean a slower gear speed.
