4.3, if the force is evenly distributed across all the cells, in proportion to the mass of each cell, then the internal motions of the cell don’t matter. The system doesn’t even need to be rigid or nonrotating. You can get away with using total force and center-of-mass velocity. ...

Both the peak variables (r = 0.94 – 0.99 for peak force, r = 0.83 – 0.91 for peak velocity, and r = 0.90–0.94 for peak power; p < 0.001) and the mean variables (r = 0.96–0.99 for mean force, r = 0.87–0.89 for mean velocity, and r = 0.93–0.96 for mean power; p < ...
(4) escape velocity near a black hole, (5) several relativistic orbit details are derived in the strong field regime and found to be consistent with GR and also the observed shadow of the M87 black hole. Curved space effects such as gravitational time dilation or Shapiro delay cannot be ...
In a turbulent flow the drag force is proportional to the momentum change of the fluid, which, in turn, is proportional to the mass of fluid whose velocity is changed in a unit time and to the velocity change of the mass. Therefore, we have: F~(πρr2v)(v) or F~πρr2v2 It is...
(2.5–3 s). As a result, the average forward velocity (30.0 ± 2.3 μm/min) is relatively slow after consuming much time on deformation recovery. Optimizing the structural design or increasing the actuation magnetic field are promising strategies to improve the locomotion velocity. ...
is the time of initial particle impact, and vS=vR−(vR·n)n is the sliding velocity. The integral in the first term in (3.19) represents the relative tangential displacement of the particles. When |Fs|>Fcrit, the sliding force expression (...
With added foot stiffness (ΔK), there was a shift towards slower fascicle velocity at the time of peak plantar flexor force. At the greatest stiffness (ΔK = 65.6 N/mm), the soleus fascicle was actually lengthening during peak force production. P-values indicate the main effect of ...
assuming that the velocity does not change with time in the analysis. The rotational acceleration of the big-end mass (equation [6.186]) as well as the linear acceleration of the small-end mass plus the mass of the piston (equation [6.191]) are now known. Therefore, the magnitude of the...
