Inverse Square Law

  1. Nov 17, 2003 #1
    This question came up in my textbook : Describe an example of a force you have experienced that follows the inverse square law. I couldn't think of any that I have "experienced", since I don't think that I have "experienced" the force of gravity that shows it is a inverse relationship.

    Eh, it's just wording. They didn't ask for you to have experienced an inverse square law, they asked for a force that you have experienced, that follows an inverse square law. Gravity is a force that you have experienced, that follows an inverse square law.

    The electric force in Coulomb's Law also adheres to the inverse square law and is one that you've experienced if you've ever been shocked (i.e. static electricity).
