Pendulum Bobs

Pendulum Bobs

Product Code : JA-PLE-4121

Pendulum Bobs (SKU JA-PLE-4121) are small metal weights with a hook for hanging on a thread, used as the swinging mass in simple pendulum experiments. These pendulum bobs for the simple pendulum experiment are supplied in brass or iron, and JaincoLab makes them for school and college physics laboratories that need class sets for mechanics practicals.

Specifications

The bobs are listed in two materials, brass and iron, and each bob has a small hook fitted for suspension from a thread or string; the number of bobs per order is confirmed on the quotation.

Applications of pendulum bobs in physics practicals

In school and college mechanics practicals a pendulum bob is hung from a rigid support on a light thread and set swinging, so that students can time the oscillations and relate the time period to the length of the pendulum.

  • Measuring the time period of a simple pendulum for different thread lengths
  • Plotting length against the square of the time period and finding g from the graph
  • Showing that the period does not depend on the amplitude for small swings
  • Comparing brass and iron bobs to show that the period does not depend on the mass of the bob

Scope of supply and ordering

The listing covers pendulum bobs in brass or iron, each with a suspension hook. Accessories such as thread and stands, spares and quantities are confirmed on the quotation.
