Impulsive Juggling

Experiment #14 from Physics with Video Analysis

Education Level
High School


In this assignment, you will be considering the catch–throw process as a slow collision between a juggler’s hand and a ball. In particular, we would like you to verify the impulse momentum theorem in a typical catch-throw process and the value of the Earth’s gravitational acceleration constant.


In this activity, you will

  • Carefully obtain y vs. t data for the center ball for the entire video clip, which includes a catch-throw segment and another segment showing the ball’s free rise and fall.
  • Choose an analytic function that you think ought to fit the free rise and fall data.
  • Perform a curve fit on your data.
