Finding the result of a collision

  1. Jul 16, 2010 #1
    I am trying to figure out how to correctly model a collision between two objects. My original plan was to get the force of impact and use that to get the result of the collision, but apparently you need the result of collision before you can find the force of impact.

    How would I find out what the result of a collision is without the force of impact? Are pre-calculated constants used, like in friction?

    Thanks! These were the formulas I was looking for:
    v1 = (u1(m1-m2)+2*m2*u2)/(m1+m2)
    v2 = (u2(m2-m1)+2*m1*u1)/(m1+m2)

    I have another question along these lines, but I'll make a new thread for it.
