The discussion centers on the work done by a radial force on a particle moving along a circular path. The key conclusion is that despite the presence of a radial force, the work done is zero because the force is perpendicular to the direction of the particle's instantaneous motion, which is tangential. The calculations indicate that while the distance traveled is πR, the work done by the radial force does not contribute due to the angle between the force and the displacement being 90 degrees.
PREREQUISITESThis discussion is beneficial for physics students, educators, and anyone interested in understanding the principles of work and energy in circular motion contexts.

dinhjeffrey said:tangential, oh so the work done would be by the tangential force, not the radial force?
