acute Posted March 21, 2019 Author #355 Share Posted March 21, 2019 If you want a pool ball to swerve to the left, you hit it on the left. If you want a soccer ball to swerve to the left, you kick it on the right. Can anyone explain this?

If you want a soccer ball to swerve to the left, you kick it on the right. Can anyone explain this? (Please show your sources, references, academic studies, working, crossing out, etc) I'm not going to explain it fully, but in sports that use a prolate spheroid you you may get an intuitive understanding of what's going on. But first let's look at cricket just to establish some terminology. A bowler can get a ball to move in various ways: Swing is conventionally caused by the way the seam interacts with the air. Not relevant to your question. Seam is natural deviation when the seam hits the pitch. Again this is not relevant. Spin is caused by the rotation of the ball when it hits the pitch or playing surface. Drift or swerve is caused by the rotation of the ball moving through air. The Magnus Effect. The snooker ball, IMO, is spinning or interacting with felt. The soccer ball is swerving or undergoing the Magnus Effect. You can see the difference in Aussie Rules or Rugby League (it's not used so much in Rugby Union). A right footed "banana kick" will curve to the right in the air. But, will curve to the left along the ground. Edited March 21, 2019 by Golden Duck 2 1 Link to comment Share on other sites More sharing options...
Unfortunately Posted March 22, 2019 #358 Share Posted March 22, 2019 Why is it that scientists are still unable to definitively explain why animals (including us) yawn? 2 Link to comment Share on other sites More sharing options...
purrrpetrator Posted March 22, 2019 #359 Share Posted March 22, 2019 (edited) Because, while they're already fully aware of the reason for why we yawn in response to a yawn -- or even at the suggestion of one (btw, i yawned reading that!) -- they still can't offer even one reasonable scintilla of explanation for why we even yawn in the first place?
