The video tutorial explains screws as simple machines, describing them as metal bars with grooves used to fix, raise, or make holes in objects. It highlights screws as inclined planes wrapped around a bar, facilitating the movement of objects between different levels. The tutorial covers practical uses of screws, such as in container lids and light bulbs, and introduces the Archimedes screw, which moves water and drains mines. The video concludes with a reflective question on the similarities between inclined planes and screws.
