Pendu-problems!

Physics phriends....


Try these fun and informative problems related to all things pendulum:

1.  A simple pendulum is 1.5-m long.  How long will it take to complete one swing (a period)?

2.  A simple pendulum is 15 cm long.  How long will it take to complete one swing?  Watch units, and keep in mind that g is in m/s/s.

3.  What is the general effect of gravitation on the period of a pendulum?  If you did a pendulum experiment on the Moon, how would the results vary?  On Jupiter?  At high altitudes on Earth?

4.  You are designing a grandfather clock to swing once every 2 seconds.  How long should it be?  This will require a bit of algebra, and may be challenging at first.

5. Research what makes a simple pendulum "simple."  What assumptions are made for a "simple pendulum?"

6.  Read all about pendulums on physicsclassroom.com, if you have time.
