https://mocomi.com/ presents: What is a Pulley? Pulley is a simple machine and comprises of a wheel on a fixed axle, with a groove along the edges to guide a rope or cable. Pulleys are used to reduce the time and energy taken to lift heavy objects. Here, Load = the weight of an object Effort = the amount of force required to lift or move this object. When you put two or more wheels together, and run a rope around them, you have created a great lifting machine. As you add more pulleys, you increase your mechanical advantage and it becomes very easy to lift the same load. The trade-off is that as you increase the number of pulleys, you require a greater amount of rope to achieve the same result. Since you have decreased the effort needed to lift the load you have to apply the force for a longer period of time. Understand the mechanism of the simple machine, the pulley. Understand and learn about how these machines make work a lot more easier and less time consuming with the help of this animated learning module for kids. #WhatisAPulley #SimpleMachines #Science To learn more about what is a pulley and how it works go to: https://mocomi.com/pulley/ For more fun learning physics videos and articles visit: https://mocomi.com/learn/science/phys...
