⚖️ The Little Lift: Lever and Fulcrum Science Film (3D)

A 60-second five-act 3D science film: a 12.0 kg crate, a 1.60 m effort arm and a 0.32 m load arm show that distance does the work of a lever. Captions explain the fulcrum, the force at each end and the limit that the lever gives no free energy. Ideal massless rigid lever with a frictionless pivot.
