Help warehouse workers lift crates by 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. Solve a range of lifting problems by using combinations of worker numbers (force) and pulley numbers. This learning object is a combination of three learning objects in the same series.
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 that the amount of work needed to lift an object is constant and the greater the load, the more work required to lift it
Students identify mathematical relationships between mass, force, distance and work.
