Here we report experimental evidence that the mathematical relationships describing the steady state dynamics are quantitatively satisfied by the independent measurements of tip-sample forces over a broad range of experimental conditions. These results confirm the existing understanding of the tapping-mode atomic force microscopy and build confidence on the reliability of time-varying tip-sample force measurements by the torsional harmonic cantilevers.16 pages including 3 figuresInstrumentation and Detectorstext
