# 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:

- 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

- 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
