What is a Lever? - Simple Machines | Science for Kids | Educational Videos by Mocomi

https://mocomi.com/ presents: What is a lever? The lever is one of the most basic forms of a machine. They help us lift loads with lesser effort. Even though this looks simple there are many things going on in order to lift the object easily. A lever can be described as a long rigid body with a fulcrum along its length. Load : The object you’re lifting. Fulcrum : Point at which the lever pivots. Effort: The force applied to make the object move. We use levers in so many of our day to day activities. They are classified into three categories depending on the relative position of the load, fulcrum and force. The 1st Class Lever – where, the pivot is in between the effort and the load. The 2nd Class Lever – where, the load is between the fulcrum and the effort. The 3nd Class Lever – where, the effort is between the fulcrum and the load. #Lever #SimpleMachines #Science To learn more about levers go to: https://mocomi.com/lever/ For more fun learning physics videos and interactive articles visit: https://mocomi.com/learn/science/phys...
