Homework questions to turn in Thursday

Please finish these questions/problems - try them all - and be prepared to turn this in to me in class on Thursday.

1.  What is a "simple pendulum"?  What makes a simple pendulum "simple" or why do we call it simple?

2.  Calculate the period of a simple pendulum with a 0.5-m long length:
a.  on Earth
b.  on the Moon, where g = 1.7 m/s/s

3.  The acceleration due to gravity on Jupiter is about 2.5 times greater than that of Earth.  Without calculating, how would the period of a pendulum be different on Jupiter (compared to Earth)?

4.  Draw the approximate shape of the graph for period vs. length of a pendulum.

5.  A little bit of algebra may be required - try this, even if algebra isn't your strongest skill.  You want a pendulum to swing with a period of 2 seconds.  How long must it be?

6.  What is the current standard of the meter based on?
