Newton's first law of motion

  1. Oct 11, 2011 #1
    1. The problem statement, all variables and given/known data

    Newton's first law of motion deals with inertia of bodies. According to this law, " Every body continues in its state of rest or of uniform motion in straight line, unless compelled by an external force."

    2. Relevant equations



    3. The attempt at a solution
    My question is , " How spontaneous decay occurs in heavy elements resulting in alpha, decay and gamma emission, without any external force acting on it"?

    The first law says that a body continues in its state of motion unless acted on by a force. In this case, there are two bodies: the particle and the body that the particle was previously attached to. There are forces that arise when a decay event occurs. The forces cause the particle to fly away at great speed and the body to which it was previously attached recoil.
