The reverse part is wrong. Reverse swing includes swinging the ball towards the shiny side. This happens because the air leaves the rough side earlier than the shiny side due to pockets of air spaces created in the worn out leather of the ball. In your video the ball is swinging away from the shiny side in the reverse swing which means there is a technical flaw in your explanation.

Air can't leave rough side faster than shiny side... Laminar flow is more consistent than turbulent flow... Here I am talking about physics not swing...

@viveksundaram9550

In general you're right. Laminar flow is usually faster than turbulent flow. However, what happens in case of a very old ball is that the turbulent flow that is on the very rough side doesn't travel the same distance as the laminar flow does. It leaves the ball way before traveling halfway around the ball. I hope I'm able to explain this without a diagram.

2:10 turbulent side pressure jyada hoga aur laminar side mein kam. You are saying opposite. According to bernoulli equation, total head is the sum of pressure head, velocity head and datum head. So if your velocity head is more, then your pressure head will be less for same total energy head.

That explains why the ball dips in with the shiny side while reverse swinging as Wasim explained.

Physics & Flud Mechanics 😊 Absolutely Right 👍

Sarfaraj Nawaj of Pakistan first used reverse swing against Australia and toot 7 wickets spending only1 run, He then taught this technic to Imran khan, later bowlers like Waquar Yunus, Wasim Akram, Aquib Jawed and Shoeb Akhtar reached this technic to a high level. Pakistan won many matches against great teams like India, Autralia, West Indies and England only by this technic although their batting was very weak. It was Imran Khan who made this technic public when a complaint was lodged by Alan Lamb against Pakistan team in England. Scientists of that time have given a very bizarre formula of physics to deliver reverse swing which even they could not throw any ball doing reverse swing.

Yes.....Fluid Mechanics....🔥🔥

If you play in humid conditions as is the case in India and UAE then reverse swing comes very early into play but if sky is cool and clear then ball stays hard for longer time as in uk and Australia or newzealand. However the turbulence actually travels with sportsmen in the form of practice. They also call it timing.

Good ..but Little tough to understand via physics methods Also explain scrambled seam bowling method whr ball stay low..slow..and some time move little but whr batsmen get difficulties to hit the ball..its useful in final overs in limited over match

Superb explanation!!!

Baaki sab kuch to thik tha lekin intro kitna gazab ka diya anchor bhai ne. Saare international aur domestic fast bowlers ko pata hota hai iske peeche ki science ka. Ye aap logo ke liye nayi baat hogi.

There is a theory called Bernoulli's principle. Which stats that the sum of AREA+ VOLUME+ VELOCITY (A+Va+ Ve) will remain constant in a motion of fluid. This whole explanation is not accurate. Agar seam angle pe rakhne se hi ball swing ho toh cricketers ball ko chamkana chorr kyu ni dete. Ball swings even with straight seam as you said. Explanation: So when you polish only one side of ball (which fielders do after each delivery) and keep other side rough.. The Air flow/ speed/ velocity is higher on the shiny side as compared to rough side. So what Bernoulli's principle said sum of AREA (pressure)+ VOLUME+ VELOCITY remains constant in a fluid motion... here we have velocity at two different ends, and other two factors (Volume of and Area of ball is still not changed). Now we can't change area of ball, so the only thing will adjust accordingly is Volume of Air to keep equation balanced at both ends of ball (shiny and rough). Now on the shiny side Velocity of Air is high that means Volume of Air will be less (to balance the equation). And similarly on the rough side Velocity of Air is Low that means Volume of Air will be higher at Rough end. That will result in, Rough side with higher VOLUME of air will have Higher pressure as well, similar shiny side will have low VOLUME of air and will have lower pressure... that means Higher pressure side will push the ball towards lower pressure (shiny side). This is the one and only reason the ball swings in the air towards shiny side. The phenomenon this video is talking about is Seaming of ball in Air.... There is basic technical difference in Seaming in Air, Seaming from Pitch and Swinging in Air. These are three different things and this video is talking about Seaming in Air.

Sir ab balu (sand) kaise banta h es par video banaye

I think Lallantop should be very careful as it was for this episode. It’s very risky to be wrong with a misused technical term.

Shiny side pressure high kaise ho skta us side to flow laminar h to air velocity tej hogi or velocity inversly proportional to pressure.

Please make video on why tractor rear wheel are big as compared to front wheel
