What units should I use for mass and rotational speed?

Mass should be entered in kilograms and rotational speed in revolutions per minute or radians per second, depending on the input fields provided by the calculator.

Can this calculator determine the actual battery capacity of a flywheel system?

No, it estimates the theoretical kinetic energy storage capacity based on mechanical parameters; actual usable energy will be lower due to system inefficiencies.

Is the energy output affected by the flywheel's material?

Yes, material properties influence the moment of inertia and maximum safe rotational speed, which in turn affect the total energy storage capacity.

Does the tool consider energy losses from friction or heat?

No, the calculator provides an idealized estimate based on input parameters; real-world systems will have lower output due to friction, bearing losses, and heat dissipation.
