How much work? LabObjective: We will generate a lab that requires work to done using various amounts of force. We will create a lab report to determine how to solve to for work.

Work=Force * Distance

Procedure:1. Collect needed materials

1 metal pan1 piece string1 spring scale1 Triple Beam Balance3 or more objects of various massLab journal / pen or pencil that works1 meter stick1 piece of chalk

• 2. Estimate which object will require the most work to move it a pre-determined length. Record in journal

• 3. Measure out 1 meter on top of lab table, mark start and end with chalk

• 4. (Teacher will Model how to set up lab) connect string onto end of metal pan

• 5. attach spring scale to end of string, put pan at start line, record amount of force at start

• 6. use spring scale to pull metal pan across table till it passes the end line, record force used at end of pull

• 7. Continue steps 4-6 using a different object in the pan each time, record findings

• 8. Use information gathered to solve for amount of work done

• 9. Record answers in chart.• 10. Use information gathered to answer

questions to follow.•

Questions to Answer…• 1. Were your estimations at the beginning of the lab

correct? Explain• 2. Which object required the most work to make it

move? Explain Why?• 3. Which Object required the least amount of work

to make it move? Explain why?• 4. Tell me how this information can be used in your

every day life.
