Homework Statement



My teacher said he wants us to know the other term for rotational KE. I've googled it and sifted through my notes but I can not come up with another name for it. I know this is a dumb question, but that seems to be all i have been asking lately.

Could he be fishing for "angular kinetic energy"?
 
It could also be called "angular kinetic energy". Could this be what he is looking for?

EDIT: Beat me to it jackie!
 
Well the fact that 2 of you came up with the answer independently kind of tells me that its right. I googled that and it seems to be the same thing.

Thanks a ton guys. Go1 is that a French Fry aviator you got there? kinda looks like that bad computer guy from tron.

I think it is actually the guy from Aqua Teen Hunger Force (a show on Adult Swim).

Starting with the mass considerations #m(t)# is mass of water #M_{c}# mass of container and #M(t)# mass of total system $$M(t) = M_{C} + m(t)$$ $$\Rightarrow \frac{dM(t)}{dt} = \frac{dm(t)}{dt}$$ $$P_i = Mv + u \, dm$$ $$P_f = (M + dm)(v + dv)$$ $$\Delta P = M \, dv + (v - u) \, dm$$ $$F = \frac{dP}{dt} = M \frac{dv}{dt} + (v - u) \frac{dm}{dt}$$ $$F = u \frac{dm}{dt} = \rho A u^2$$ from conservation of momentum , the cannon recoils with the same force which it applies. $$\quad \frac{dm}{dt}...
