i have not posted a blog on this site since the very end of last quarter and since then the swim season has started and almost come to an end. weeks ago we learned the impulse momentum theorem which states that an impulse acting on a system changes the systems momentum. a good example of this would be somthing in swimming called a flip turn, for those unfamiliar with the concept a flip turn is done at either end of a pool during a race to turn around and continue. during a flipturn the swimmer does a summersault in the water while moving which decreasing the momentum of the swimmer. mid turn the swimmer's feet will cme in contact with the wall and they will push off quickly this acts as an impulse as it transfers the forward mometum back into the other direction.
