마그누스 효과 EBS 물리 강남 대성 물리 고재근

마그누스 효과를 CG를 사용하여 설명하였습니다.
이춘도 : 깔끔한 설명 감사합니다. 처음에 공 아래쪽을 찼다는 설명보다 공을 위에서 아래로 내려다보는 장면인 것 같은데 진행방향 좌에서 우 기준 A는 왼쪽 B는 오른쪽이고 공 오른쪽 면을 오른발 안쪽이나 왼발 바깥쪽 부분으로 차서 왼쪽으로 휘어진다고 설명해주시면 이해하기에 좋을것 같습니다. 감사합니다.
김치킨 : 선생님 감사합니다!!
창TV : 깔끔한 설명,기억이 확실히 되네요.
풋살보이 Futsalboy : 그림과 같은공이 회전하면서 지면에 충돌할때의 경우의 힘의 원리에 대해 설명해주실수있나요? 볼을 역회전을 걸어서 던지면 바닥과 충돌직후 튀겨지는 높이가 낮은게 궁금해서요
김나영 : 도움이 잘됐다ㅎㅎ

민트초코 : Strange Applications of the Magnus Effect
Not8909 : Imagine if we got a machine to spin it real fast
NJ : Another Mangus effect is that the opponents resign immediately when they see e4 Najdorf on board by Magnus.
Kevin Luo : I would totally click on strange applications of the magnus effect.
Zyper Zillamore : I like how the effect of changing the name of this youtube video to a more clickbaity one drastically increased the number of views.
This is something that people tend to look at. This is either being curious, wanting to watch something cool, or just being a fan of Veritasium.

The Magnus effect: a curved ball explained: from fizzics.org

A spinning curved ball, caused by the Magnus effect is loved and hated by players of all ball games. Top spin makes the ball dip and side spin makes it curve or swing. The video provides examples and an explanation of the cause of the Magnus effect.

Vladimir Hatter : The last experiment is excellent!
Dean Gulston : Very good explanation! Very easy to understand. I really liked that last experiment with the cylinder. Such a cool effect!
Prateek Tathicherla : Would the transitional velocity of the ball affect the lift on the ball? I would imagine the wake would be longer and the resulting force would be larger in magnitude as well. Also it seems that the Magnus force is not perpendicular based on this explanation but only that the force contains a vertical component causing the lift. How does the horizontal component of the Magnus force affect the ball as it would seem that the ball would have to go faster based on the direction of the horizontal force.
K Mundendy : Thank you for the explanations. I would love to know would happen if the experiment is redone either with a more heavier(say metal) tube or done in vacuum.
Abuydabab : I've recently had a homework to describe this effect. Most articles on the internet say that it's about Bernoulli's law, but i also found several videos (for instance Yours and on Veritasium youtube channel) saying that this effect is more probable to be connected with 3rd Newton's law.
As you wrote below in comments it is hard to measure size of the contribution of each of these effects.
Sadly my teacher doesn't know that fact and Bernoulli's law is the answer he wanted to see.

Thanks for explanation
