The bobbin-wound hanging string can be extended up to 180cm.
Observe how the weight, size, and length of the pendulum affect its period and discover any regularities in the motion of the pendulum.
The weights are screwed in and can be easily replaced.
The hanging string is wound on a bobbin, making it easy to adjust the length.
A protractor (included) for measuring the swing angle can be attached to the tip of the support.
Two types of wooden balls are included as weights, along with an iron ball. You can visually understand that the pendulum period does not depend on the weight or size of the pendulum. Pendulum support: Aluminum, φ10, length 185mm, approx. 72g (with bobbin)
