Now that summer is practically here and watching my parents open the pool, I decided to do this physics blog on swimming. Swimming relates to physics a lot more than you think. Newtons first, second, and third laws play a huge part in the physics of swimming.
Newtons first law shows the difference between static and dynamic forces and why it takes extra forces to get through two different forces. A static forces is when a body is at rest it stays at rest. The movement you feel once you get your body to move it you overcoming the static force. A dynamic force is when a body in motion wants to stay in motion. Newtons second law gives us the explanation as to why someone can swim faster than others. For example, if someones mass is equal, then it would be all about the amount of force they use to take off. Newtons third law states for every action there is an equal and opposite reaction. When swimming and doing the breast stroke,the water moves down the side of you. The equal reaction would be pushing the water back on you while the opposite reaction would be the reason why you are moving forward.
This proves that physics is everywhere, no matter what you do!
