I. Conservation of Momentum I I. Nick Rotruck II. Objective: a. Prove the Law of Conservation of Momentum. III. References: Momentum Conservation Principle: http:// www.glenbrook.k12.il.us/gbssci/phys/Class/momentum/u4l2b.html Concept of Conservation of Momentum: http://www.grc.nasa.gov/WWW/K-12/airplane/conmo.html Conservation of Momentum Lab: http://www.physics.northwestern.edu/Lab/cem2.pdf IV. Procedure: 1. Use the medium-sized and smallest balls. Align the heights of the balls so the line joining their centers is parallel to the bottom of the arc. 2. Place the two photogates in the notches at the bottom of the arc. 3. Connect the photogates and set the timer to interval mode. 4. Set the stop at the highest point along the arc. With the target ball at rest, drop the projectile ball and record the time it takes to pass through the light beam coming out of the collision. Record the time under column “Target after collision (t p ).” 5. Push the memory button and record the time under heading “Projectile before collision (t 0 ).” 1
