    Throw ball to wall (action) it comes back (reaction). what is between action and reaction? is reaction necessary? is there any physical action having no "reaction"?

    basically it means that the kinetic energy of the ball needs to go somewhere
    some of it gets absorbed by the wall, some of it goes towards deforming the ball, and the rest is the ball bouncing back (unless it's very heavy ball and a very flimsy wall, in which there will be movement in the wall as well)

    Action and reaction are only legitimate in the context of Newtonian physics. Quintillions of quantum happenings negate the concept of an equal reaction.
