Kinetic Energy Calculator

Step 1: Add one or more components by clicking on the appropriate diagrams

Bar

Disk

Cylinder

Teeth

Components


Step 2: Enter RPM & Calculate KE

MOI: ft lb/sec^2 Weight: lbs

RPM *:

Kinetic Energy: ft poundals or joules

* For accurate results, the entered RPM should reflect the actual output RPM of the weapon, not the theorecitaly output. Air resistance, friction, battery and motor selection, and other factors will contribute to the final output RPM of a weapon, often drastically. These factors are outside the scope of this calculator.
