Conservation of Angular Momentum and Kinetic Energy

Share with:


Imagine a rod 2 meters long fixed at its center, 2 identical masses are placed 0.5 meters away on opposite sides , as the rod spins they slide towards the edges , according to the formula k.E.=0.5*I*ω2 the kinetic energy decreases , but since its a closed system why does the kinetic energy decrease ?


 

Answer:

The decrease in KE accounted by the work done in displacing the masses
