The coefficient of restitution

  1. Nov 30, 2008 #1
    Hello everyone
    I learned the coefficient of restitution in school.
    I wonder if the coefficients of restitution of two bodies are different in the cases with and without external force acting on the two bodies.
    Also, do you guys have any reference paper about COR?
    Thank you so much!!

    The COF is related to implsive forces between two objects and external forces have no influence.

    As clem was saying the coefficient of restitution will be the same since it's a static value between two materials.
