Surface gravity is denoted by \(\kappa_1\) and is defined by where \(r_+\) is the horizon radius, \(r_+=R_S\) for the Schwarzschild spacetime, \(u^t\) is the time component of the 4-velocity. The 4-velocity of a free particle instantaneously at rest in the Schwarzschild spacetime: The only component of the 4-acceleration different from zero is \(a_r\)
