Inquiry: Collisions

Purpose: To analyze the conservation of momentum.

Procedure:

We will use the applet below to experiment with momentum. An elasticity of 0% means completely inelastic and the balls will stick together. An elasticity of 100% means completely elastic and kinetic energy will also be conserved along with momentum. After you have tested your momentum ideas attempt the following 2 problems. You can see the results of these two scenarios within this applet to check your answers but you need to show work in your notebook.

Inquiry Questions:

  1. Create the following settings for a completely elastic collision and show detailed work on how to calculate the final velocities of both balls.

    Red Ball mass 2.0 and velocity 10.0
    Green Ball mass 3.0 and velocity -6.0


  2. Create the following settings for a completely inelastic collision and show detailed work on how to calculate the loss of kinetic energy.

    Red Ball mass 2.0 and velocity 10.0
    Green Ball mass 3.0 and velocity -6.0
