    Hi! Can someone please explain fundamental forces to me? My teacher is kind of useless 😒 all I've got so far is that they involve exchange particles which somehow exist because of borrowed energy. Also what particles feel what force? I think I understand gravity and electrostatic attraction but what about strong and weak force? Thanks 😊

    So the 4 forces act on different molecules. Gravity acts on everything with a mass, weak acts on everything, electrostatic acts on anything with a charge and strong acts on anything made up of quarks ie hadrons.
    For ranges, gravity and electromagnetic are infinite, weak is 1/1000x diameter of a proton and strong is half the diameter of a nucleus but is really strange.
    For strengths, strong force is repulsive between 0 to 0.5 femtometers and 10^38 x stronger than gravity (attractive) between 0.t and 3/4 femtometers.

    It's a force that accounts for the interaction between charged particles.

    does that mean the force between electrons and protons?

    Yes but not limited to. It would also include ions such as Na+ to Cl- or anything with opposing charges

    Yes, and, as the above poster mentioned, the force between anything carrying an electric charge.
