Elastic collision 1D HTML5


The conservation of momentum  as well as the conservation of kinetic energy define the elastic collision.   You can change the masses and speeds of the colliding objects by clicking on them. The position of the center of mass is indicated.

Click and drag on a mass to set a new velocity.

Learning goals

  • To show how useful it is to consider the reference frame of the center of mass in studying  an elastic collision.
  • To perform a ticker tape analysis.
