Pulley Lab

In class:

The purpose of this lab was to recognize the relationship between the amount of force used, and the distance used to lift a certain mass. To lift the mass we created pulley. Lifting the mass with the pulley used much less force than without one, which resulted in the final thought that more distance = less force. This is because work remains constant. To graph the two different tests, we used a bar graph like the one shown below. In the graph, we show the relationship between force and the distance used to pull the mass. As the amount of force used increases, the distance is much less. The equation we created from our information is A=FxD, meaning the area shaded on the graph is the result of the amount of force used multiplied to the distance used as well.

Connection to the Real World:

You can connect the information found in the lab, and doing simple tasks that involve something like a hammer. A hammer is similar to this because you are adding distance to the swing you use to hit a nail down into a piece of wood. Heres an example: Try hitting a nail with your hand, and then try hitting one with a hammer. Hitting the nail with the hammer is much easier because the added distance takes less force (it also doesn't destroy your hand).
