Abstract

A (3+1)-dimensional asymptotically flat Kerr black hole angular speed Ω+ can be used to define an effective spring constant, k=mΩ+2. Its maximum value is the Schwarzschild surface gravity, k=κ, which rapidly weakens as the black hole spins down and the temperature increases. The Hawking temperature is expressed in terms of the spring constant: 2πT=κ-k. Hooke's law, in the extremal limit, provides the force F=1/4, which is consistent with the conjecture of maximum force in general relativity.
