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

• 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

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.
