Homework Help: Work-rotational motion

  1. Mar 30, 2005 #1
    work--rotational motion

    This question is related to rotational motion....


    The work done by an object in rotational motion is [tex]\int^{\theta_f}_{\theta_i}\tau d \theta[/tex]

    Does this mean [tex]W=\tau(\theta_f - \theta_i)[/tex]?

    Yes.

    Compare to [tex] W = \int_{x_i}^{x_f}{F}{dx} = F(x_f-x_i)[/tex]

    yeah, that's what I was thinking, thanks for the verification
