Demonstrate conservation of momentum by launching a ball into a pendulum. The height the pendulum will increase is directly proportional to the marble's initial energy. This offers students an opportunity to use trigonomtry, kinematics, and angular momentum formulas to determine the initial velocity of the marble. Use of a a photogate measures actual velocity of the marble to provide the lab with an alternate method of determining energy. Students can conduct the lab both ways and compare the two results.
Ideal for for AP, B and C, IB, and advanced honors physics courses.
