- Flexible high-tensile stitching thread for the suspension.
- Supplied as components for students to assemble.
Technical Specifications
| Specification | Value |
|---|---|
| Bob | Brass, typically 25mm diameter |
| Stand | Metal retort stand with heavy base |
| Clamp | Boss head for height and length adjustment |
| Suspension | High-tensile stitching thread |
| Assembly | Separate components for student set-up |
How It Is Used
Students hang the bob from the boss head, measure the length to the centre of the bob and time a set of small swings to find the period. Repeating for several lengths and plotting T² against L gives a straight line from which g is worked out using T = 2π√(L/g).
Frequently Asked Questions
What is the Simple Pendulum Apparatus used to find?
The period of a pendulum at different lengths. From the readings students confirm that the period depends on length and calculate the acceleration due to gravity, g.
Does the Simple Pendulum Apparatus come assembled?
No. It is supplied as components, the brass bob, thread, boss head and retort stand, so students set it up themselves.
