ii) under uniform circular motion, radial forces do no work and therefore produce no power because the force is perpendicular to the particles velocity. A radial force with position vector r originating from (0,0) for a particle of mass m in uniform circular motion is expressed by :F = m dv/dt r = rcos(theta) i + rsin(theta) j and v = dr /dtw (omega) = dtheta /dtVerify no power is produced by a radial force . . . by performing the operation P = F . v = 0in the above equation i think the period is the bigger dot meaning F dotted into v. . . but any help wold be appreciated
