@pilotmike,
Don’t get too worked up. People don’t always ‘get it’ straight away. There have been numerous attempts on this thread to explain basic physics in different ways to chopjock, and the message has finally sunk in it would seem. So we all contributed to his/her final realisation.
@chopjock, well done for admitting you were wrong. You did make a pillock of yourself, but the important thing is that you have publically acknowledged this and learned something.
