    What you find on the following site might be of help to you. There may be a lot more to it than what you see below. But, at least it is a start for you. Hopefully, our Science Expert, Capuchin, will come along and also offer some information.

    Types of Forces

    From the site above:

    Quote:

    Types of Forces
    A force is a push or pull acting upon an object as a result of its interaction with another object. There are a variety of types of forces. Previously in this lesson, a variety of force types were placed into two broad category headings on the basis of whether the force resulted from the contact or non-contact of the two interacting objects.

    Contact Forces

    Frictional Force
    Tension Force
    Normal Force
    Air Resistance Force
    Applied Force
    Spring Force

    Action-at-a-Distance Forces

    Gravitational Force
    Electrical Force
    Magnetic Force

    One more thing, there are also links to questions about forces on the bottom of this page. You might want to click on them and see what other information there is.

    I think Clough has it covered.

    The "contact" forces that he lists are actually macroscopic interpretations of the "Action-at-a-Distance" forces.

    I would say that the 4 fundamental forces are:

    Gravitational Force (responsible for attracting macroscopic objects together)
    Weak Force (responsible for radioactive decay)
    Strong Force (responsible for holding atoms together)
    Electromagnetic Force (responsible for almost everything you can think of that the other 3 aren't responsible for)

    (Some people would group the electromagnetic and weak force together as the "electroweak force", but that may be a little too advanced for you)
