Four Fundamental Forces?

  1. Jun 16, 2011 #1
    1. The problem statement, all variables and given/known data
    Could someone give me some examples of the four fundamental forces? (Not their definitions)


    2. Relevant equations
    None..


    3. The attempt at a solution
    -Strong nuclear force:

    -Weak nuclear force:

    -Electromagnetic force: Starting a car? Picking up paperclips with a magnet?

    -Gravitational force: Tides?

    1-as u might know protons repel from from each other strongly so how are they bonded together is the nucleus well its because of the strong nuclear force which binds quarks together to form protons and neutrons and it binds protons and neutrons together to form the atomic nuclei.its mediated by a particle called gluon.
    2-the weak nuclear force is responsible for the decay of atoms and particles and it is mediated by 2 particles z and w.
    3- the electromagnetic force is responsible for the repulsion and attraction of charged particles-electrons and protons.
    4-the gravitational force is responsible for combining atoms together to form planets stars galaxies , and for the earth orbiting the sun and moon orbiting the earth and for the tides....
