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.
- Open the simulation Collision Lab.
- From the menu on the right, select: Show Values
- In the yellow window below, click on "More Data"
- Activity 1: Elastic Collisions in one dimension. Ball 2 is initially at rest.
- On the menu to the right, slide the indicator all the way to the right for a perfectly elastic collision.
- For the given masses and initial speeds of the two balls, determine the velocity and momentum after the collision.
- Activity 2: Elastic Collisions in one dimension. Balls 1 and 2 initially moving in the same direction.
- Ball 1 and Ball 2 initially moving in the same direction
Activity 2: Elastic Collisions in one dimension. Balls 1 and 2 initially moving in the opposite direction.
- Note that when Ball 2 moves opposite to Ball 1, its velocity and momentum are negative!
Activity 3: Inelastic Collisions
- On the menu to the left, slide the indicator all the way to the left to ensure perferctly inelastic collision.
- The Java Applet comes from the PhET Interactive Simulations at the University of Colorado, Boulder.
- Some activities are based on the "Laboratory Manual, Physics 231 - 232" by Walter Wimbush, Northern Virginia Community College, 2008.
