Newton's law of motion

  1. Feb 2, 2007 #1
    1. Why is inertia called an inherent property?

    2. According to third law of motion, specify the action and reaction while hammering a nail.

    Action is hammering but whats the reaction????

    What do you mean by the "action is hammering" The hammer strikes the nail: what is the action, and what is the reaction in this situation?

    reaction:Ouch when he misses???

    action: The force of the hammer exerted on the nail
    reaction: The normal force the hammer exerts back onto the hammer

    Inertia is an inherent property since it is simply something all things (matter) have. For example, inertia is an inherent property of mass, because without it, everything would be prone to acceleration with virtually no force applied.
    (My explanation of inertia isn't that thorough).

    Nail pushes back on the hammer >.<

    inertia is an inherent property because all matter posses it, it is not unique to a special type.
