Accelerated Motion

Experiment #2 from Vernier Video Analysis: Motion and Sports

Education Level
High School


How can we use mathematics to express the way an object moves when it is speeding up? The velocity of the object is constantly changing, rather than a steady value. In this exercise, you will apply curve fits to graphs of position vs. time and velocity vs. time for a fan cart. You will use the curve fits to determine the parameters of the motion.


In this experiment, you will

  • Use video analysis techniques to obtain position, velocity, and time data for a cart that is speeding up.
  • Apply curve fits to your graphs to determine how to mathematically describe the motion.
  • [Extension] Analyze an additional video of an object undergoing constant acceleration.
