1 Stretching a Spring

Hooke's Law

Mark the beginning and end positions of several different masses. Compare the end positions of masses that are multiples, such as double or triple. Video
2 Simple Pendulum

Pendula

The length of the pendulum is adjustable. A timer can be used to measure the period.

3 Physical Pendulum

​Physical Pendulum Set

Hang the pegboard on the nail from some random hole. Hang weights from support hole and mark its path using the chalk. Repeat with different holes until an intersection of lines is achieved. Mark this spot as the center of mass.  
4 Mass on a Spring

Springs and Oscillators

Set up equipment as shown and place a hooked mass on the spring. Pull down and release to start simple harmonic motion. If desired, time the oscillation and calculate the frequency. Change to a different mass in order to change the frequency.

5 Coupled Pendula

Coupled Oscillations

Two pendula hang from a flexible metal frame. Start one pendulum oscillating. The pendula will pass the energy back and forth. A third pendulum can be added.
