Linear Momentum in Collisions

Goal: To investigate the Law of Conservation of Linear Momentum in collisions.

Simulation Used: Collision Lab from the PhET at the University of Colorado.

Preliminary Settings.

β Open the simulation Collision Lab.

β From the menu on the right, select: Show Values

β In the yellow window below, click on "More Data"

Activity 1: Elastic Collisions in one dimension. Ball 2 is initially at rest.

β On the menu to the right, slide the indicator all the way to the right for a perfectly

elastic collision.

β For the given masses and initial speeds of the two balls, determine the velocity

and momentum after the collision.

Question: Is the momentum conserved? Yes

Question: Is the kinetic energy conserved? Yes

Momentum final= 0.70 kg.m/s
