by Texas Instruments - Simulation Lesson


  • Students will explore the electric force between charged objects.
  • Students will observe how the force depends upon the magnitude of the two charges and the distance separating them.


  • attract
  • charge
  • distance
  • force
  • magnitude
  • Newton (used as a unit)
  • ratio of forces
  • repel

About the Lesson

In this lesson, students will explore Coulomb's law by manipulating the magnitude of two charges and the distance separating them.

As a result, students will:

  • Observe that charges with like signs repel and charges with opposites signs attract.
  • Relate the magnitude of the force the charges exert on each other to the product of the two charges and to the inverse square of the distance separating them.
