Thank you, Arturo. The equation I have in mind is one used to find
kinetic energy, which is a scalar, from torque, which is a vector: mrg
= mr^2 alpha theta. Here, m is mass, r displscement, alpha angular
acceleration, and theta angular displacement in radians, a pure number.
Thus, mrg is torque, a vector and mr^2 alpha tetha is kinetic energy, a
scalar. Dimensionally, I think the equation is correct.
