Help warehouse workers lift crates using a rope and pulleys. Explore relationships between mass, force, distance and work. Notice that pulleys change the direction of a force and make it easier to lift loads. Identify the number of workers needed to lift a range of weights. This learning object is one of three objects in a series. The series is also packaged as a combined learning object.
Objective
Students identify that pulleys change the direction of an applied force.
Students identify mathematical relationships between mass, force, distance and work.
