Screws and Pulleys | Motion and Simple Machines | The Good and the Beautiful

Описание: Is a screw a simple machine? What about a pulley? And what do these two machines have to do with each other? Both screws and pulleys are simple machines that help make work easier, often securing or lifting heavy objects. Learn about the screw, a small and simple machine used in buildings, homes, toys, cars, planes, and more. 🔩 Then explore how a pulley system helps us construct buildings, open garage doors, and even operate ski lifts! 🏗 Discover the importance of screws and pulleys in this video from Lesson 11 of The Good and the Beautiful's Motion and Simple Machines science unit.
