When the ball is older and there is an asymmetry in roughness the seam no longer causes the pressure difference, and can actually reduce the swing of the ball. Air turbulence is no longer used to create separation point differences and therefore the lift and pressure differences. On the rough side of the ball there are scratches and pits in the ball's surface. These irregularities act in the same manner as the dimples of a Golf ball: they trap the air, creating a layer of trapped air next to the rough side of the ball, which moves with the surface of the ball. The smooth side does not trap a layer of air. The next layer of air outward from the ball will have a greater velocity over the rough side, due to its contact with a layer of trapped air, rather than solid ball. This lowers the static pressure relative to the shiny side, which swings the ball. If the scratches and tears completely cover the rough side of the ball, the separation point on the rough side will move to the back of the ball, further than that of the turbulent air, thereby creating more lift and faster air flow. This is why a new ball will swing more than a old ball. If the seam is used to create the turbulent air on the rough side, the tears will not fill as quickly as they would with laminar flow, dampening the lift and pressure differences.
Cricket balls are more massive than golf balls (because they're bigger and denser).
This means the balls can impart more force, which over distance means they can do more mechanical work.
when a spinner bowls he use his fingers to turn the ball, while when a pacer bowls it turns due to grass in the pitch.
Becasue it has air in it and golf balls have parts of pig brain in it and not air..
This is because the cricket ball is more heaver and bigger than the golf ball so it imports more force
it also swings...
Hey friends i am Shivam , and i think that the cricket players need speed to even play cricket as if they will not have speed they couldn't play cricket. In cricket, speed is needed every where to even take a run by the strikers quickly or to catch the ball far from the fielder by running in speed to get the ball by the opponents team. So speed is too important in the game of cricket.

They allow the ball to fly, and make it aerodynamic.
in my hands!!!!
no tape ball doesnot have seam position thats wahy its speed is slow
In international cricket, simply a speed gun is used on the boundary line. However, in standard club cricket, you can video the delivery, note the distance, and time how long it takes the ball to get to the end of the pitch from the start of the delivery.
The maker of the golf ball the maker of the club and you.
I believe so.
The speed is measured by radar from the batsman's end as the ball leaves the bowlers hand.
One possible reason is to reduce the impact on his hands due to the speed, force and hardness of the cricket ball.
