I was watching a show on TV that showed how many lbs. of force a basketball players uses to jump. In this case, the player pushed into the floor with 1400 lbs. of pressure to jump 4 feet in the air. That's all good and well, but does this mean when the player comes down and lands he will impact with 1400 lbs.? So if I were to jump with, say, 1000lbs. of pressure, do I land with 1000 lbs. of impact into the floor? Just curious, thanks everyone. In other words, is the jump the same as the impact?
