Coulomb's Law

Experiment #12 from Vernier Video Analysis: Conservation Laws and Forces

  • Make qualitative observations about the electrical interaction between various charged objects.
  • Use an examination of forces in static equilibrium to determine the magnitude of the electrical force between charged objects.
  • Use video analysis techniques to determine the relationship between the magnitude of the electrical force and the distance between two charged objects.
