Figure 2. Pause-free translational velocity as a function of opposing force.

Data points are the mean velocities for all measured traces at each force (N = 54). Error bars represent the standard error of the mean. The solid line is an exponential fit of the form $v\left(F\right)=v_0\exp \left(-\frac{F·\tilde{x}}{k_{B}T}\right)$.
