Elastic collision 2D 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. Note that the trajectory of the center of mass is not disturbed by the collision.

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.
