Question

Quizplus · Accepted Answer

When a fighter "rides with the punch," it means that they move in the same direction as the punch, increasing the time of contact of the blow. By doing this, they decrease the force applied to their jaw and reduce the likelihood of injury. Additionally, since the momentum of the punch is conserved, increasing the time of contact decreases the change in momentum, effectively reducing the amount of energy transferred to the fighter's jaw. Therefore, choices B and C are the best options.
