pushing defensive linemen

This past weekend our football team played the St. Louis Crusaders.  We ended up losing the game.  But in losing i learned a lot, not only about football, but also about physics.  What i learned about football was that sometimes even when you play your hardest you can still lose.  What i learned about physics was that f=ma.  I discovered this while i was blocking a big defesive lineman from St. Louis. My coach told me that i was moving my guy too slowly so i realized that if i want to move him faster then i will need to accelerate him more.  and since he is the same mass as before i will need to push him with more force.  this thinking can be represented by this equation F=mA, where the upper case bolded letters represent the values that must increase for me to move the lineman faster. 

Blocking

This week we played Punahou in a football game.  We ended up losing the game, but I learned a lot from the game.  I play offensive line on our team.  These are the guys who block the defenders from getting to the quarterback.  While I was blocking #90 from the other team i realized that he was bigger than i was.  This meant that when he hit me he would move less from the impact because his mass was greater than mine.  It is just the same concept in the fly and the car problem.  Both the car and the fly experience the same impact because of Newton's third law of motion: for every action there is an equal and opposite reaction.  The reason the car keeps moving forward and the fly is smashed is because the car has a greater mass.  When i realized this was the case when i was blocking i knew that in order to move the defender i would have to apply more force in the form of punches with my hands.  This is when i began to punch his harder and i was able to block him easier.
