I am totally new to physics and do not study it what so ever. I do however find it extremely interesting and one question that has always puzzled me is - If some thing is moving and it comes to a complete stop, at what speed was it travelling at right before it stops? what ever speed you come up with surely you can half that speed again and again. The only conclussion i can come up with is that it never actually stops or it's never moving to begin with. Someone please help me with this. Share your thoughts with me. If you think I am talking rubbish please tell me with an explanation as to why. Regards Dave.
