Homework Help: Centripetal force

  1. Mar 15, 2005 #1

    do any of u guys knw what is the relationship between the centripetal force and frequency, mass, speed, and radius of a rotating object?

    thx a bunch :tongue2:

    {Mass} = m
    {Speed} = v
    {Radius} = r
    {Frequency of Rotation (in Hz)} = f
    {Angular Frequency (in radians/sec)} = ω = 2*π*f

    {Centripetal Force} = m*v2/r
    {Centripetal Force} = m*(2*π*r*f)2/r = m*r*(2*π*f)2 = 4*π2*m*r*f2
    {Centripetal Force} = m*r*ω2
