Work Investigation Lab Report

Work Investigation
Purpose: In this lab, you will work with a partner to investigate the force required to do work on an aluminum plate as you pull it at different angles.
Materials:
1 aluminum plate
String
1 kg mass (you might need to use two 500-gram masses)
1 spring scale

Prediction:
Before you begin, sketch a graph that shows your prediction of the relationship between the force and the angle you pull it at. In other words, what patter do you think the graph will demonstrate?

Procedure:
1. Place you aluminum plate so that its narrow side aligns with the edge of your table.
2. Add a 1kg mass to the plate or two 500-gram masses.
3. Attach you spring scale to the string loop.
4. Pull on the plate at an angle of zero degrees (parallel
