On Monday, the defending NBA champions, Cleveland Cavaliers, played the runner up Golden State Warriors for the second time this season. The Cavs were looking for their 5th straight win in a head to head match up against the Warriors, however, the Warriors (with all 4 1/2 of their All-stars) handily defeated the Cavilers in this match up. The controversial play of the game was a Flagrant foul by Draymond Green on Lebron. The question is, did Lebron Flop? We can answer this question using physics and momentum.
As we know, when two objects collide, whether an elastic or inelastic collision, momentum is always conserved. Therefore, if we calculate the momentum of the players before and after the collision, we can decide if Lebron flopped or if it was all from Draymond. According to an article from Wired.com author Rhett Allain calculates the momentum of the players. Based on the players listed masses and video analysis he found that this was the data:
"LeBron before the collision = +548 kg*m/s
