video - Pendula, Spring and SimplePurpose:Introduce students to the hanging mass from a spring or a string systems.Procedure:SPRING PENDULUM - mass hanging from a springOne can calculate k for the spring from F = kx by hanging different masses from the end and noting the amount the spring stretches. Different masses and springs can be used for the pendulum, while noting similarities and/or differences. For example:
  SIMPLE PENDULUM - mass hanging from a stringFor the simple pendulum, one can measure the length of the string, then calculate the period T. Verify by timing 10 oscillations. Different masses can be used for the pendulum, while noting similarities and/or differences. For example:
