Learn Science through Sports – 8

One of the phenomena that you see on the field quite often is the swing of a football or a cricket ball when it travels at a good speed through the air. This happens due to two reasons - first being the spherical shape of a ball that allows air to flow all around it and the second being the surface of the ball. Let's look at how the surface of the ball affects its flow through the air! Watch the video!

So you see, a smooth surface enables smoother and faster flow of air across the surface of the ball and provides lesser resistance. Sport is one of the best examples to see the phenomenon of air swing and resistance!
