Free Fall and Pendulum Apparatus

Code: 4134.70

A complete solution for the study of free fall and pendulum motion

The apparatus is designed specifically for the study of free fall due to gravity and the study of the Law of the Pendulum.

It consists of a vertical column with a graduated scale and an electromagnet, mounted on a triangular base with levelling screws and a basket for the falling spheres. The acceleration of free falling bodies, defined as “g”, is studied by measuring the time necessary for a falling body to move a fixed distance on the graduated scale. The apparatus can be used with Electronic Timer. To use a large LED display for classroom use, the Altay Large Display (code 2236.50) is an ideal choice.

EXAMPLE OF USE: The Laws of the Pendulum

Study of the oscillations in a pendulum.

The Electronic Digital Timer is an ideal tool to study the Laws of the Pendulum. We can also use the Electronic Oscillation Counter to measure the period of the pendulum (T) to easily verify the following formula.
