CENCO® AP Physics Lab 7: Conservation of momentum - Ballistic Pendulum
Educational Materials Physics Educational Materials AP Physics Learning Activities
The Ballistic Pendulum Lab is a classic experiment that determines conservation of energy and angular momentum.

  • Multiple Launching Positions
  • Easy-To-Read Protractor
  • Extraction Device for Ball
  • Students Determine the Initial Velocity of the Marble
  • Purpose for Students: to Practice Trigonometry, Kinematics, and Angular Momentum Formulas
Teachers show conservation of momentum by launching a ball into a pendulum. The height to which the pendulum increases is directly proportional to the marble’s initial energy. This offers students an opportunity to use trigonometry, kinematics, and angular momentum formulas to determine the initial velocity of the marble. A photogate measures the 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.
