الوصف
This is a pendulum motion law apparatus, a type of physics education kit used to study the principles of a pendulum.
Features
It is used to investigate the relationship between a pendulum's period and variables such as its length, mass, and amplitude. The apparatus includes a curved rule to measure the angle of swing and a measuring tape to adjust the length of the pendulum. It typically comes with different masses (bobs) that can be attached to the pendulum. The apparatus is designed for use in conjunction with a stopwatch to measure the time period of each swing.
