Pulleys: add more pulleys

Learning Material  |  Interactive Lesson  |  RAR




Description
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 that the more pulleys used, the greater the load that can be lifted with a given force.
Students identify that efficient use of pulleys reduces the amount of force needed to lift an object.
Students identify mathematical relationships between mass, force, distance and work.
