Today, we’ll see how springs behave and learn about Hooke’s Law through an exploratory lab. In the lab, you’ll try to answer the following questions:
  1. Is the force that a spring applies constant?
  2. If so, what is the force for a given spring? If not, how does the force change?
  3. Is there energy associated with a spring? In other words, can a spring do work?
  4. If so, how can you calculate the work done by a spring?

Homework:  Make sure that you complete your lab graph.  Attempt to answer the lab questions above.  You can put the answers to these on the back of the half piece of graph paper I gave you.  I will collect these little pieces of paper.  Read in your textbook Section 5.2 on pp. 147-149.  Try problems from Chapter 5 #44, 49, 56, 57.  Unit test on work and energy on Thursday, January 25th.
