In this experiment, you will be:
- working separate from your partner
- analyzing a spring and elastic band that is different from your partner's
- collecting data with both a mechanical spring scale and a digital force sensor
- recording data into a table as well as onto a graph at the same time
In working with the digital force sensor
- The software is run from a link under the Physics lab web browser favorites, ForceIntro
- The software is designed to give correct readings when the range switch on the force sensor is set to 10 N
- The sensor needs to be set to read zero for zero force. Do this by pressing the "zero" button in the software with no force applied.
- You are encouraged to become accustomed with the software and try different things with it. This software will be used in a variety of experiments
In working with the mechanical spring scale
- The scale has an unusual increment that is difficult to read. Take your time with making measurements even to the extent of recording in your notes what you saw.
- Use the Newton measurements of the scale
- Although your experiment is expected to follow a linear relation (Hooke's law), this may in fact only hold in a limited region.
- Always separate analysis from data. Record data as honestly and completely as possible. Then, as a separate step, consider the data in context of your objective (the analysis or results step).
- Position is data as it is directly measured. Displacement is a result, calculated from two position measurements.
