A question about "opposite and equal reactions" Newton's third law of motion says "For every action there is an opposite and equal reaction". So when I throw a rock at a brick wall (action), that rock bounces off that wall (opposite and equal reaction). But if I jump up and while in the air and my shoes are not touching the ground when I throw a rock at a glass window (action) that rock smashes through that window (reaction but not opposite since that rock goes in the same direction I threw it). It appears Newton's third law of motion is not accurate. Can someone clarify this third law of motion? Did I disprove it or is Newton somehow correct? Please explain.
