Throughout our lives, we interact with many things such as doors, cars and other objects. Now that we are over half-way through the year we have a good sense of all aspects of motion, Kinematics, Forces, Energy, and Rotation. I wanted to talk about flip turns because they incorporate different types of motion, especially rotation and torque.
When a someone swims freestyle or backstroke and they are approaching a wall and need to continue swimming, the most efficient way to do so while conserving speed and power is to perform a flip turn. When a swimmer prepares to do a flip turn, they lower their head to look at the bottom of the pool. They do this so that their chest follows their head more naturally and makes for a fast and easy flip. When the swimmer leans into the flip they will tuck their knees into their chest to decrease their turning radius. Once the swimmer is on their back, they will push of the wall with their hands over their heads in what is called streamline. This is the most effective way of swimming through the water while creating the least amount of drag. Finally once the swimmer has emerged from under the water they will continue swimming.
