Lab 2.1 Newton Rides a Bike: Newton's Second Law (20 points)
How is acceleration affected if either the mass of the system or the force used to pull the bike changes?
In this lab students investigate how the acceleration of an object is related to its mass and the force exerted on the object, and use their experimental results to derive the mathematical form of Newton’s second law.
You will write up this lab in a Google Docs document or another "sharable" digital format.
The work which is documented should be clear enough that others can follow it, understand it and if necessary, repeat the experimental procedure so as to verify the results. It is a public record which is documented with the expectation that others could understand it. The ability to thoroughly document and to keep clear, understandable records of one's work is a key skill that the professional scientist must develop.
The Data section should include an organized and labeled record of the measurements. Both measured and calculated data should be listed; work should be shown. The Conclusion/Discussion should identify the acceleration determined from each method. An error analysis should be performed; the accuracy and precision of each method should be compared; reasons for such conclusions should be explained.
Questions to be addressed in the Conclusion:
These questions address velocity vs. time graphs, so it may be a good idea to provide example graphs when answering these questions.
