Title: Work In Motion Lab
Lab Question/Problem: How do you measure work in motion?
Hypothesis: If I move a heavy object, it will take more work than moving a lighter object.
Materials: Scissors, copybok, a shoe, a plastic ring, string, and a push pull meter.
Procedure: 1. Use your push-pull meter to lift three objects from the floor to your desktop.
Observations:

In which case was the most work accomplished? The most work was accomplished when we were lifting the shoe.
In which case was the least amount of work accomplished? The least amount was accomplished when we were lifing the scissor.
Data Analysis/Results: (add table from Activity Sheet 2, Part A.)
Object
Distance Moved
Amount of Force
Scissors
92 cm.
2 in.
Copybook
92 cm.
3 in.
Shoe
92 cm.
8 in.
Conclusion: You measure work in motion by using a push pull meter which shows how much force is needed to move an object a certain distance.
