Physics 2: Newton's Third Law

While swimming one night this weekend, I began to ponder what was propelling me forwards in the water. Through some research and logical reasoning, I realized this was because of Physics! According to Newton’s Third Law, “To any action there is always an opposite and equal reaction; in other words, the actions of two bodies upon each other are always equal and always opposite in direction.” This means that for the force I pushed my hands and feet against the water, an equal and opposite force was created to push me forwards. The harder and faster I pushed then resulted in me going faster or creating a greater and equal opposite force. I am once again surprised to find another thing I always did to be related to physics, and have learned how to become a faster swimmer by grasping its underlying concepts.

Friction

This weekend at bowling practice, i experienced the properties of friction. It hit me when I hit the ground; friction is not to be taken for granted while practicing this sport. Friction is, "A force that resists the motion of one object sliding past another". In bowling too much friction creates the poblem of an unsmooth glide towards the pins, resulting in some bowling complications. Too little friction however suchas, if you step past the line onto the oiled lane creates more disasterous problems. I learned this through esperience at a bowling match when I accidentaly stepped over that forboding line. This creates the meeting of my already smooth bowling shoes (to resist drag) and the oily lanes. By doing so, the amount of friction was greatly reduced, resulting in embarassment as I slipped and fell. Friction is very important in the sport, bowling, and many other activities we take part in.
