Power is given as, P=Wt……(i) where,Wis work done andtis time. Now, work done is given as, W=Fd……(ii) where,Fis force anddis displacement. Therefore, on comparing the two equations the equation for power can be written as, P=Fdt Now, we know that velocity is given as, v=...
The results obtained are as follows: 1) Force-velocity relations calculated after correcting the effect of inertia of the forearm and apparatus were well fitted to Hill's equation in different age groups (r >0.994). 2) The ratios of a/P_0, which characterize P-V relation, were almost ...
An important consequence of the rigorous derivations of the electromagnetic force and power of the extended charged sphere with arbitrary velocity is that the integrated self electromagnetic force, and thus the Lorentz-Abraham force equation of motion, is shown to transform as an external force ...
The Hill equation was fit to the data obtained for each individual fiber (r2 > or = 0.98). For the SED group, fiber force-velocity parameters varied (P type IIa > type I; maximal shortening velocity (Vmax, defined as y-intercept of force-velocity relationship), type IIx = type IIa >...
Generally, in many cases, the direction of velocity is not in the direction of force, then we use the scalar form of eq(a): P = Fv. Q2: Does Speed Affect Power? Ans: Yes, speed affects power. The more the speed of a body, quickly a task will be done in less time, so more ...
The Power was coming incorrect from the Force. And regarding the use of F - mg, I'd remember it for the future. Thanks. OK. BTW the basic equation for the variable-mass problem is Fext = m dv/dt + v dm/dt - u dm/dt v = velocity of c.g. of "large" mass u = velocity...

Toward the end of the nineteenth century Lorentz modeled the electron by a spherical shell of uniform surface charge density and set about the difficult task of deriving the equation of motion of this electron model by determining, from Maxwell's equations and the Lorentz force law, the retarded...
