Hi I’m Kitty Stars!!😸😺
Me and my class are exploring pulleys!
What is a pulley you ask? Well a pulley is a system that pulls an item with down force, up. Pulleys help lift heavy things up with up force. Pulleys use down force because it’s easier to lift something with down force then, with up.
this was is what they look like!
Also there are two types of pulleys, a fixed and a movable pulley, The one in the video is a fixed pulley!
