Physics of flip turn. Physics of swimming part 5

- For the physics of the flip turn this is all you need to know. L = rmr
This video consists of three parts; the first one will explain this equation, the second one will explain the best flip turn technique and the third one what you can do to improve your flip turn.
What you need to know for L or angular momentum is that is stays the same throughout the spin. So when I rotate on my chair I have a certain velocity let’s say 2 km/h , that is V. A mass that is 75 kilograms and a distance of the mass in my extremities to the axis of rotation, lets say 100 cm. That means that the angular momentum is 15,000. That number will not change. So what happens if I change the distance of my extremities by making it smaller say 30 cm? Since this number must not change, the mass hasn’t change either, the velocity increases! to 3.33333333333 km/h. That’s how ice skaters can do this…
But what does that have to do with the flip turn? Well when you are swimming you have linear momentum but when you do a flip turn you transform that into angular momentum and this equation applies! The tighter you make the flip turn the faster you will turn! Just look at these examples.
In order to improve your flip turn then you must make your body into a small ball and for that you will need certain mobility to get into this position. Maybe you don’t have the mobility to be in this position, So try doing this for 30 seconds several days a week for a month and you will see improvements. If you want to practice the speed of your flip turn try holding to a wall and flutter kicking. When you are ready do a fast flip turn focusing on being tight, small and fast!
Another important aspect of the turn is the third law of newton.
Basically you need to convert that angular momentum into linear momentum again by pushing the wall. The wall will push you with the same amount of force that you push it. So make sure to not slow down coming into the turn because you will use that force to push yourself the other way, and make sure you use those leg muscles to push off the wall strongly!
If water gets in your nose when you do a flip turn or if you want to learn the basics of a flipt urn, watch the videos on this playlist.
Watching videos alone will not improve your swimming, you need hours of deliberate practice. If you want to practice but you don’t have a coach or you need workouts, we have a new workout for you every time you want to go swimming! This will help you be regular with your swimming practices and will keep you motivated. We offer three levels of difficulty the easiest being around 1,200 meters or yards each practice, then the moderate with around 2,400 and the hard around 3,500. If you are interested find out more at
