Meterstick Equilibrium Physics Lab

This lab introduces the concept of mechanical equilibrium to beginning physics students. They will come to see how the equilibrium rule applies to all nonmoving objects at rest. Materials needed per group are a meterstick, a 1kg mass, and two digital scales. Two colored pencils are optional, as they will assist in line differentiation for the graph they will construct. If colored pencils are not available, just use a pencil and pen instead. (And pray they do not need to erase the pen lines.)
