They sure can leave a mark! <img src="/styles/default/xenforo/smilies/whistling.png"  class="smilie" loading="lazy" alt=":whistling:" title="Whistling    :whistling:" data-shortname=":whistling:" />  However, the "force" remains the same.  Force = Pressure * Area The last variable yet unmentioned is "time".  If one takes twice as long to bring a moving object to a stop, it takes half the force.  However, the "impulse" remains the same.  The opposite is if one doubles the contact time two colliding objects with the same force, the impulse is doubled and the momentum transferred is double.  This is why one should follow through the swing on a baseball or golf club.  If one can keep the ball touching the bat/club longer, there will be more momentum (hence velocity) transferred. Not a clue of why Sunshine disagreed with you.  Was it your string theory comment? My head hurts.</blockquote>
