The video explains the concept of levers, which consist of a lever arm and a fulcrum. Levers help move loads with minimal effort by adjusting the fulcrum's position. Examples include a wrench, where the nut is the load and the collet head is the fulcrum, and a door, where the hinge acts as the fulcrum. The placement of handles away from the hinge reduces the effort needed to open the door.
