To outswing a cricket ball. Hold the ball with its seam inclined marginally towards the slip quadron. Keep the shiny side of the ball inside. With this arrangement and very normal speed around 130-135 kph, you can get the ball swing away conventionally.
A cricket ball swings in the air due to the interaction between its seam and the airflow around it. The seam disrupts the airflow on one side of the ball, creating a pressure difference that causes the ball to move towards the side with higher pressure, resulting in swing. Factors like the condition of the ball, the angle at which it is released, and the speed at which it is bowled also play a role in swing.
The bowlers and the teammates used to make the ball shine on one side. When the bowler bowls with the seam , if he shining side of the ball is on one side then it cuts the air due to friction and the ball moves on the same side.
I believe that spin is exerted on to the ball by the hand, swing is how the ball moves in the air and turn is what the ball does off the pitch. If you're asking about cricket.
well u actually have to hold ur fingers in a particular angle on the seam of the ball. To swing the ball into the wickets hold your middle and index finger across the seam and angle the ball into leg slip. This can only be done with the help of the shiny side and with loads of practice.
Actually, in my experience, slightly oldish cricket balls tend to swing more than new balls. This happens when you keep one side clean by shining it / rubbing it on your shirt / sweater / trousers and let the other side become dirty / dull. If you then bowl with the seam in an upright position, the difference in air resistence beween the clean and dirty sides makes the ball swing. If done correctly, the ball will swing from shiny side to dirty side - reason being (supposedly) that the shiny side travels slightly faster through the air than the dirty side. Thus, if you hold the ball with the shiny side to the left, you will swing the ball from left to right (an inswinger to a right-hander) and vice-versa (an outswinger to a right-hander) - generally considered more diffiuclt to achieve.
By "polishing" an older ball (say 30-40 overs) on one side only, especially in damp weather, what happens is that the polished side has less air-friction and thus moves faster than the unpolished side, causing turn in mid-air.

Reverse swing in an exact opposite of conventional cricket ball swing. It normally occurs when the ball gets a little old. Depending on weather conditions, pitch nature and environment around, the ball normally starts getting old after 20 to 25 overs. In Australia and South Africa, the ball normally starts reverse swinging around 40 to 45 overs. While the ball starts getting old, players on the ground (especially bowlers) try desperately to keep the shine on one side of the ball while the other side of the ball keeps getting rougher. Once there is a significant difference of shine and roughness on both sides of the ball, the ball starts swinging towards the shiny side. This is called reverse swing, however, it is not natural and the bowlers have to really work hard to deliver reverse swing. When the ball becomes very old - around 40 or more overs old - it begins to swing towards the shine. This is known as reverse swing- which means a natural outswinger will become an inswinger and conversely, an inswinger into an outswinger.
Cricketers Spit on otherwise known as "shining" a cricket ball as they would like their fast bowlers to be able to swing the ball in later overs. They only shine on side and leave the other side "rough". When bowling, the bowler will bowl with the seam (middle of a cricket ball) in an upright position and when the ball is delivered, the air will travel faster past the smooth, shined side of the ball and on the other side there will be drag and air will get caught on the rough side... this difference in wind speeds passing the ball results in ball "swining"- movinging in the air.
A backhand swing in tennis is using either one or two hands on the opposite side of your dominant hand to hit the ball. For example, if you have a two-handed backhand and you are right handed, you would swing at the ball with two hands on your left side. Thus, your backhand swing is on your left side with two hands.
In cricket, Bernoulli's theorem can be applied to understand the physics of ball flight. It helps in analyzing the spin and swing of the ball, as well as the aerodynamics involved in delivering different types of balls such as in-swing, out-swing, or off-spin. Understanding Bernoulli's principle can also aid in predicting ball trajectories and optimizing bowling techniques.
