Inertia (kg*m²)
Diameter Centrifugal Force
RPM Surface Speed (M/sec)
This is a simple Javascript energy calculator for small flywheels. It computes kinetic energy values for ideal disk or ring flywheel configurations. Most real flywheels will fall somewhere in between due to the hub and spokes. Flywheel mass and diameter can be specifed in Metric (grams/millimeters) or English units (ounces/inches). Output is Metric only. Check Metric or English, enter mass, diameter and rpm values then click COMPUTE.
