Can tennis ball swing?
With a cricket ball, it does have to do with friction. The relative flow velocity is greater on the smooth side and lower on the rough side. This difference in flow velocity provides a sideward "lift", following the Bernoulli principle.
With tennis or table tennis, the difference in flow velocity is achieved by means of spinning the ball. However, with a cricket ball, a fast bowler does not spin the ball. He holds the seam essentially vertically and delivers the ball in that orientation.
Under overcast conditions, the air becomes thicker due to low temperature and high humidity.The air offers more resistance to the ball.The swing is more under such conditions
