- On this episode of Physics of swimming we will go over Kinetic and potential energy and why I think Adam Peaty is like a cobra.
“You can think about the physics of moving objects in two different and equally acceptable ways: in terms of forces, or in terms of energy.”
In the past physics of swimming videos we looked at them in terms of forces, now it will be energy. Kinetic energy is the energy of motion ("kinetic" means motion) Potential energy is stored energy. Energy can be stored in chemicals, by compressing a spring, or by doing work against gravity.
Ok so let’s bring it back as it relates to swimming. When you are diving you have two kinds of potential energy. The first is gravitational potential energy. You convert that energy into kinetic as you are in the air and gravity brings you down to the water. This type of potential energy is found in a smaller scale while you swim butterfly. When you lift your torso and arms above the surface, you convert kinetic energy into potential and then back to kinetic as you quickly are brought down by gravity. Then you pass that energy through your body and down to your feet through the undulating movement of the stroke, this movement then pushes the water backwards and pushes you forward.
The second kind of kinetic energy you have on the blocks is chemical potential energy. Muscles act like springs, so the chemical potential energy of muscles is converted, by the muscle applying a force, into kinetic energy of motion.
So when you “take your marks” you stretch certain muscles as if you were stretching a spring. Those muscles have a lot of chemical potential energy which is transformed into kinetic energy as the muscles tighten and make you jump!
That is why I think Adam Peaty is like a cobra. Because when he swims breaststroke he uses his back muscles and arms to lift his torso and head high above the water. This gives him gravitational potential energy, then just like a cobra he uses his core muscles to throw his upper body forward transferring that energy down to his legs. His legs are already full of chemical potential energy when he bends them and he uses all of that stored energy to push his body forward under the surface with a speed that only this human being can maintain through a 100 meters long course.
So now you know! Swimming is all about the dance between these two types of energy and the forces that interact with our bodies. To learn more about the forces of physics check out our physics of swimming playlist by clicking here:

Thanks for watching!
Swim fast!
When your favorite swimming channel suddenly turns into a physics lesson XD
The quobra stores quemiqual energy! Cuite qunning! ;D
I wonder what's your other profession than swimming? Physics Professor? Wow!!! Your vlogs make a difference by stating how tips are grounded in science! Great job!
Not really, but I do like physics 🙂
Great!!! Was amazed with how kinetic and potential energies are applied in swimming! Never thought of it! Haha just plainly more of Biology and Anatomy :)
Now I know why I like Skills NT Swimming.👏👏👏
@@RayFliesAway same here :) happy swimming! :)
You solve my biggest mistake on swimming breastroke
1:54
how would that be considered potential energy when the springs are not being compressed?
because at the beginning u said potential energy is when you compress a spring or if you do work against gravity.
I got 2nd place at my swimming race,thx for helping me!
amazing explanation!! very impressed to me!! quiet clear. logical scientific!!! i appreciate you!!!
Excelente buena información y traducción al español gracias por tenernos en cuenta y compartir tus conocimientos saludos desde Medellín Colombia
Hello i swim with a lot of people,and when i try to breathe some water goes in any tips?
Anyway you helped me a lot with your channel!
Great video and explanation! ⚡️
How do you get those hearts?
Thank you SO much
When someone says that swimming is an easy sport XD
You've deserved a sub, keep on recording!
thank you
Great video! Subscribed.
Hi sir,pls upload a video for starting freestyle dive(leg kick) without folding a leg.(means how u kick the leg without folding during water entry in this video pls guide me sir) tq
Currently have a 1:02 in 100 yard breastorke and will try using my abs to lower my body after the pull phase.
Creative perspective 👌 This will help in the pool, thanks
평영을 코브라처럼, 애덤 피티(Adam Peaty)처럼 헤엄치세요 :: 수영의 물리학 :: 6부
수영의 물리학 이번 편에서는 운동 에너지와 퍼텐셜(잠재, 위치) 에너지를 살펴보면서 왜 애덤 피티(Adam Peaty)가 코브라 같다고 생각하는지 설명드리겠습니다.
"우리는 움직이는 물체의 물리학에 대하여 똑같이 수용 가능한 두 가지 방식 즉, 힘의 관점 그리고 에너지의 관점으로 생각할 수 있습니다."
이전 수영의 물리학 비디오들에서는 힘의 관점으로 살펴보았으므로, 이번에는 에너지의 관점으로 살펴보겠습니다. 운동 에너지는 움직이는 에너지입니다 ("키네틱(kinetic)"은 움직임을 뜻합니다). 퍼텐셜(잠재, 위치) 에너지는 저장된 에너지입니다. 에너지는 화학적으로, 스프링을 압축함으로써, 또는 중력에 대항하여 일 함으로써 저장될 수 있습니다.
좋아요. 그렇게 에너지는 수영과 관련되므로 다시 기억을 살려보겠습니다. 뛰어들기(다이빙)를 할 때는 두 가지 종류의 퍼텐셜(잠재, 위치) 에너지가 있습니다. 첫 번째는 중력 퍼텐셜(잠재, 위치) 에너지입니다. 공중에 뜨면서 중력에 의해 물속으로 떨어지면서 중력 퍼텐셜(잠재, 위치) 에너지를 운동 에너지로 변환하게 됩니다. 이런 종류의 퍼텐셜(잠재, 위치) 에너지는 접영으로 헤엄칠 때 더 작은 규모로 볼 수 있습니다. 접영에서 몸통을 들어 양팔을 수면 위로 올릴 때는, 운동 에너지를 퍼텐셜(잠재, 위치) 에너지로 변환합니다.
그런 다음 중력에 의해 재빨리 떨어지면서 퍼텐셜(잠재, 위치) 에너지를 다시 운동 에너지로 변환합니다. 그런 다음 몸통을 거쳐 쭉 두 발까지 물결치는 움직임으로 그 운동 에너지를 전달합니다, 그 움직임이 이제 물을 뒤쪽으로 밀고 그래서 몸을 앞쪽으로 밀게 됩니다.
발사대 위에서 갖게 되는 두 번째 종류의 퍼텐셜(잠재) 에너지는 화학적 퍼텐셜(잠재) 에너지입니다. 근육들은 스프링과 같은 역할을 합니다, 즉 근육 속의 화학적 퍼텐셜(잠재) 에너지는 근육이 힘을 발휘하면서 운동 에너지로 변환됩니다.
즉, "테이크 유어 마크스"(차렷) 자세를 취할 때는 스프링을 늘리는 것처럼 특정 근육들을 늘리게 됩니다. 이 근육들은 화학적 퍼텐셜(잠재) 에너지를 많이 갖게 되고 이 화학적 퍼텐셜(잠재) 에너지는 뛰기 위해 이 근육들을 수축하면서 운동 에너지로 변환됩니다!
이것이 제가 애덤 피티(Adam Peaty)를 코브라라고 생각하는 이유입니다. 왜냐하면 애덤 피티(Adam Peaty)가 평영 할 때 등과 양팔 근육을 사용하여 몸통과 머리를 수면 위로 높이 들어 올리니까요. 이 동작 덕분에 그는 중력 퍼텐셜(잠재, 위치) 에너지를 갖게 됩니다. 그런 다음 코브라와 똑같이 코어 근육들을 사용하여 상체를 앞쪽으로 던지면서 그 에너지를 아래로 다리까지 전달합니다. 그의 다리는 그가 다리를 접을 때 이미 화학적 퍼텐셜(잠재) 에너지로 가득 차 있습니다 그래서 그는 저장된 에너지 모두를 사용하여, 장수로 100미터 거리 내내 오직 이 사람만이 지탱할 수 있는 속도로, 자신의 몸을 수면 아래 앞쪽으로 밀게 됩니다.
자 이제 여러분도 알게 되었습니다! 수영이란 우리 신체와 상호작용하는 이 두 가지 종류의 에너지와 힘 사이에서 추는 춤과 같습니다. 수영의 물리학에 대하여 더 배우고 싶다면 여기를 클릭하여 이 재생목록을 확인하십시오:

빠르게 헤엄치세요!
Thanks for the video. As for the scientific explanation of the stroke etc, well not very accurate, usage of technical terms somewhat inaccurately. Good effort, praise you for trying. (From a physicist)
Is morning swim practice is better than evening swim practice ? Why?
Don’t think so
I think for men it is, simply because your testosterone levels are scientifically highest in the morning.
@@jonathandirk6132 It's easier for me to swim in the evening but there's a sort of resistance in arm movement when I swim in the morning.
Your good at science
You're
I set my 100 yd PR at 1:00.06. I haven't done a breaststroke race in 10 years because I've been focused on triathlon, but I recently got the urge to try and break sub 1 min.
Nice video but I'm a little confused...
Do you mean "elastic potential energy" instead of "chemical potential energy" ?
I thought it was the same, but I could be wrong
Someone who is good at physics taught me that elastic is all right and chemical is correct too.
Elastic is easier to imagine a spring for me :)
Thank you for your reply!
Que bueno👍 solo falta los subtitulos
Listo!
Every single frog has gotten a PHD degree.😅
👏
Thanks for making this video i had some major mistake in my breastroke
Idk what i am talking about
Allah 1 adam peaty 2
Inşallah peaty bir gün konyaya gelir onla yarışırız ınş like atın belki peaty görür
Hola ,por fa con subtitulos en español, gracias
Listo!
You're great, but you make mistakes as we all do.
The video you show or someone reaching forward and down on the arm recovery. That's not what Peaty does and that's a waste for two reasons: 1. It increases frontal drag and 2. It makes it impossible to use your shoulder rotators at the beginning of the arm stroke since your hands are already down. I hope this helps: Coach Steve Friederang, Publisher Competitive Swimmer Magazine.
Por favor subtitulado en español gracias
Listo!
Con subtítulos en español porfis
Ud sabe más inglés que yo
I learned this in physics already lol but I didn’t know this could apply to breaststroke
Thank you
