Flywheel Energy Storage Calculator vs Capacitor Energy & Charge Calculator

Two calculators for the same neighbourhood of questions. Here is what each measures, what you feed in, and where you'd reach for one over the other.

Mechanical

Flywheel Energy Storage Calculator

Calculates the usable kinetic energy stored in a flywheel between maximum and minimum operating speeds, accounting for system efficiency. Use it when designing energy storage systems or regenerative braking applications.

Answers
Usable Energy Storage (kJ)
Inputs
Moment of Inertia, Maximum Speed, Minimum Speed, System Efficiency

Capacitor Energy & Charge Calculator

Calculates the energy stored in a capacitor and its remaining energy at any point during discharge through a resistor. Use it when designing RC circuits, timing circuits, or energy storage systems.

Answers
Energy Remaining (mJ)
Inputs
Capacitance, Voltage, Discharge Resistance, Discharge Time
