Ideal pendulum simulator
Explore how pendulum length and gravity affect the ideal period. The animation uses a small swing and does not model damping or a large-amplitude correction.
Your inputs
Start with the example values, then replace them with your own. For tables, keep the vertical bar separators and use a dot for decimals.
This simplified educational calculation has stated assumptions. Do not use it for navigation, engineering safety or other safety-critical decisions.

How it works
Small-angle period T = 2π√(length / gravity). Friction, finite amplitude and flexibility are excluded.
Worked example
These sample results use the original example inputs in the form. They do not change when you edit your inputs; your own result appears in the workspace.
- Ideal period: 2.0061 seconds
- Cycles per minute: 29.9093
Read the result carefully
Results depend on the values and assumptions shown above. Change one input at a time to see its effect. A blank or unavailable result means the data does not support a calculation; it is not zero.
