Vernier physics experts Josh Ence and Fran Poodry demonstrate how to use the Go Direct® Motion Detector to teach Newton’s second law and help students investigate the relationship between force, mass, and acceleration. In this video, they explore two methods for investigating Newton’s second law: (1) using a cart and fan system and (2) using a modified Atwood setup. 

What you’ll learn

  • How to set up and use the Go Direct Motion Detector for precise measurements of position, velocity, and acceleration in real-time
  • Techniques for collecting and analyzing data to help students develop a mathematical model of Newton’s Second Law
  • Methods for guiding students through data interpretation, including graphing techniques and error analysis to reinforce critical thinking skills
