Momentum #3

This is a video of UFC 129 when Lyoto Machida fought Randy Couture. Lyoto won the fight with a knock out due to a kick to Randy's jaw. Lyoto Machida trained martial arts ever since he was a little kid and mastered all types of strikes. Lyoto is around 205 lbs. and fights in the light heavy weight division. That means when Lyoto kicks it's with a large mass. So when Lyoto threw the kick it had a high velocity and mass which projected a lot of momentum to Randy's jaw. Because Randy wasn't expecting that type of unorthodox kick from Lyoto he failed to protect himself. Since the time of the momentum transfer was short there was a lot of force put into his face that caused him to get knocked out. Even UFC fighters know their physics!
