Webb4 sep. 2024 · The Rf Value. The distance a particular molecule, or spot, travels relative to the distance travelled by the eluting solvent is called the Rf value. The Rf value ranges from 0 (indicating the molecule did not move up the plate at all) to 1 (indicating the molecule traveled all the way up the plate). Can Rf value be negative?

Again, shoving toward the axis of rotation isn't going to cause any rotation either and, once again, the mathematics supports this intuition. Since sin (180°) = 0, the value of the torque is once again τ = 0.
