After learning about Newton's 3rd Law, I can now identify one scientific reason why my favorite boxer, Floyd Mayweather, hand might have been swollen during his fight with Canelo Alvarez. Whenever, a boxer, Floyd Mayweather, lands a punch let's say in his opponents face, as shown above, the opponents face exerts the same amount of force on Floyds hand, which can cause his hand to be swollen or even fractured . The reason his opponents head moves sideways and Floyd's arm does not is because Floyd's entire arm is more massive than his opponents head, causing his opponents face to move because of the applied force. So whenever an object/human moves backwards when two forces are acting on another it is not because of the difference in the magnitude of the forces, but because of the difference in mass of the two objects.
