:: : : : : Your wording suggests that you're assuming that the rotational kinetic energy of the wheels is more significant than the translational kinetic energy of the rest of the vehicle.

What with their engine management system trying to keep the revs low and their resulting low rotational kinetic energy, the the OP's model may well have stalling problem if it fits into this category.
23.
A nontrivial angular momentum potential \ Phi _ { J } arises for rotating sources due to the rotational kinetic energy which, because of mass-energy equivalence, can also act as the source of a gravitational field.
24.
The rotational kinetic energy of the whole system of moving parts is \ frac { 1 } { 2 } I \ omega ^ 2, where \ omega is the angular velocity of the moving parts about the same axis as the moment of inertia.
25.
On further examination, since the energy that we extract from these objects should create a mutual dragging effect on the spinning black hole and fractionally slow its rotation, the energy removed corresponds to the reduction in the rotating black hole's rotational kinetic energy.
26.
In space, if a force ( "'F1 "') is imparted on the end of a rod, the rod would gain both translational kinetic energy and rotational kinetic energy, and the force would be accounted for as both a translational force and a torque.
27.
However, energy has many different modes : overall linear and rotational kinetic energy, potential energy of the objects'chemical bonds ( e . g . deformation ), temperature, etc . It is very difficult to predict or measure how much energy is transferred to each different mode.

:: : : The rotational kinetic energy is actually easy to calculate ( treating the Earth as a sphere allows us to re-use others'integration ! ), and is even given in that article as an example .-- Tardis 17 : 56, 6 September 2006 ( UTC)

I think this might be a plausible mechanism for energy transfer between the planet and the black hole : Tidal forces could act on the planet, changing its spin and therefore its angular momentum, and the angular momentum of the hole would have to change to balance the books, with a concomitant change in its rotational kinetic energy.

:: Well, I think you forgot about rotational kinetic energy . . . but anyways, if I were to ignore friction, then what I wrote above would be right, except that I don't think that friction can be ignored; otherwise, why mention that it slides for a little while ? talk ) 20 : 37, 2 September 2010 ( UTC)
