Pulleys
In this Class 9 Science topic, students explore how pulleys are used as simple machines to lift loads and change the direction of effort. They learn about fixed and movable pulleys, the roles of load, effort, and fulcrum-like support, and how mechanical advantage and velocity ratio describe a pulley system’s performance. The topic connects pulley operation with work, energy, force, and everyday applications such as cranes, wells, flagpoles, and lifting equipment.
