Lacrosse games

Since it is now lacrosse season, games have begun. Within the game, physics takes place everywhere; especially on the bench, where I am! I get to stand on the sidelines and watch the game but there is so much physics involved with that. First off, I exert a force on the ground with the same magnitude of force that it forces up on me. This way, I do not go right through the ground, I am safe and secure on the sidelines. I am also facing a force downward on me which is gravity. It pulls me down 9.81 m/s^2 which is good because I wouldn't want to accidentally float onto the field! Also, I do a lot of cheering on the bench. Sound waves travel all throughout the game as I scream for our team. Along with that comes different amplitudes and frequencies. The more we win, the lower frequency comes out. The pitch in turns becomes higher. Playing left bench is very exciting because I get to have physics involved in everything that I do.
