if it convert to (non mechanical ) type of energy. for mfb question the answer was heat. like when i using my weld machine, and yes too for most of friction betwen 2 or more mechanical thing, like friction on gear, V-belt, and even it not touching one to another, like friction betwen rotor and...

again I'm using calculating using : http://www.botlanta.org/converters/dale-calc/flywheel.html Input Metric (gram, mm) Mass = 15000 Diameter = 280 RPM = 1500 Output Surface Speed (M/sec) = 21.99 Interia = 0.147 Disk KE (joules) = 1814.01 Is this the "only" stored energy on flywheel from 1500...

most are go/used to move "a thing", and finally get suck by "a thing". and disappear.. like energy mechanical we used to pushing a wall, and does the wall stored our energy? or disappear? because energy can not be create or destroy, so it just flow... wasted, unused, disappear? like a energy...

Thanks DennisN, according http://www.botlanta.org/converters/dale-calc/flywheel.html at 1300 RPM (5000 grams, dia = 283 mm) Disk KE (joule) = 463 j at 1500 RPM = 617 j is that mean, i need 617j-463j = 154 joule to regain the top speed...

Flyheel the storage energy. The transfer from mechanical energy to electric energy was equal. The situation was, i got a 1/2 hp electric motor (EM) that can turning a 5 kg flywhell (∅ 28 cm) to 1500 RPM within 10 second. (connected by gear to each other) question was: 1. at the 11 second, i...
