... The weight of a 1-lb can is the force F needed to oppose gravity: F = m·g = 1 lb, where m is the mass and g is the acceleration due to gravity. Suppose you lift the can d = 4 ft. Your work is W = F·d = m·g·d = (1 lb)·(4 ft) = 1 ft-lb. But m·g·d is the potential energy of the lifted can (see Lesson 2 ...
