lesson 2

• A fundamental law in physics that describes the electric force between two charged particles.

  coulombs law
• coulombs law

• If you INCREASE the magnitude of one of the charges, the electric force will

  increase
• If you INCREASE the distance between the two charges, the magnitude of the force will


  decrease
• attraction and repulsion between electric charges comes from a force known a

  electrostatic force
• the force that exists between electrically charged particles

  electrostatic force
• states that when a number of charges are interacting, the net electrostatic force a given charge is the vector sum of the forces exerted on it due to all other charges.

  superposition principle
• The area or field around a charge where the electrostatic force can be experienced is

  electric field
• coexists with every electrostatic charge it associates with each point in space the electrostatic force experienced per unit of electric charge by an extremely small (or infinitesimal) test charge at that point.

  electric field
• predict the behavior of the charges present in any location in space

  electric field
• can be graphically represented using electric field lines.

  electric field lines
• metal rods placed on tall structures to protect them from lightning.

• , which uses a moving belt to accumulate a large amount of charge on a metal sphere. The charge resides on the outer surface of the sphere due to electrostatic equilibrium.
