Presentation transcript:

Physics: Pulleys Lab Goals Investigate pulley systems with 1 & 2 pulleys. Discover the realtionship between the # of ropes pulling on a load and the effort required to lift that load.

1. Check to make sure the spring scale is balanced or zeroed 1. Check to make sure the spring scale is balanced or zeroed. If not turn the knob at the top to fix it. 2. Lift the load using the spring scale to find out how much force it normally takes to lift it without the aid of a lever. Record the information on a paper for later use.

We will only be conducting Part 1 of the experiment. Use the diagrams provided to you with your worksheets to help you figure out how to build the pulleys.

Record your results on the table in the worksheet Record your results on the table in the worksheet. Complete the 2 analysis questions below the tables and the worksheets reviewing pulleys systems, and calculating the mechanical advantages & efficiencies
