Introduction

When a ball falls, its gravitational potential energy is transformed into kinetic energy; likewise, after a bounce, the ball rises into the air and its kinetic energy is transformed back into gravitational potential energy. On the next bounce, this energy transfer repeats, but the ball doesn’t rise back up to the height it fell. At some point along its path, it lost energy. In this experiment, you will investigate the energy of a bouncing ball and seek to determine where, when, and how it loses energy.

Objectives

  • Use video analysis techniques to obtain position, velocity, and time data for a ball that is
    bouncing.
  • Create calculated columns of energy data to graphically show the changes in energy.
