Physics homework for next class (Wednesday)

Pendulum homework - to be turned in next class

1.  When we say the “period of the pendulum,” what exactly do we mean?

      2.  When we say "simple pendulum", what does that mean?  In other words, what does the period of a simple pendulum most depend on?

      3.  What is the basic shape of the graph for the period of a pendulum versus its length?  Please draw this.

      4.  What is the basic shape of the graph for the period of a pendulum versus the mass of the bob?

      5.  Where in the pendulum’s path does it come to a complete stop?

      6.  Where in the pendulum’s path does it have maximum speed?

      7.  Given what you know about energy, how might you describe the energy of the pendulum?

      8.  Find the formula for period of a simple pendulum.

      9.  Calculate the period of a 3-m long pendulum.

     10.  Does the period of a pendulum depend on gravitational acceleration?  If so, how?
