No. Consider a universe with 3 infinite dimensions, and consider a 2 inch x 2 inch plank with infinite length. The plank has infinite volume and yet does not occupy all the volume in the infinite universe.

The expedient thing to say would clearly be 'x is greater than or equal to zero.' :smile:

Put it on a scale, obviously. :smile:

It works like this: You have a book resting on a table. It's not falling through it or anything weird like that. It's just sitting there. According to Newton, there must be no net force acting on this book, otherwise it would be accelerating according to F=ma - in other words, it would be...

Nothing special, at least from your own point of view. From your own perspective, everything will be perfectly normal. Others observing you, however, will perceive time slowing down for you, and you will observe time slowing down for them.

To your first question, yes, I think they do just 'float' around in the metal. As for your second question, I'm pretty sure that gravity is so insignificant as to be meaningless on the atomic scale. The other forces (electromagnetic, strong nuclear, weak nuclear) are many orders of magnitude...

Away? :biggrin:

I think (I may be wrong) that it's been shown that the electromagnetic, strong nuclear, and weak nuclear forces unify at extremely high temperatures. In other words, shortly after the Big Bang, the three forces were one.

I already did! Yet you ignore that post. This whole argument is getting ridiculous. You are trying to challenge the fundamentals of Newtonian physics, and you're just plain wrong. You've been proved wrong multiple times in this thread already, and yet you seem to just ignore good advice. I don't...

Look, the numbers are irrelevant. They can be tweaked such that you get realistic values. The point is that there is an interval of contact and the ball is displaced while in contact with the club and thus there is a velocity while the ball is in contact with the club. What are you trying to...

No, it doesn't, but you chose terrible numbers. A club will never exert merely 10N. Honestly, though, the numbers are irrelevant. You can see that, choosing ANY number that you like, the ball is in contact with the club for a finite displacement. I have no idea what you are trying to argue...

The ball is displaced while it is in contact with the club. It's only displaced by a small amount before it leaves the club, but it is definitely displaced. Here, I'll give you some mathematical figures. Assume that the ball weighs .05kg and that it reaches a final velocity of 80 m/s. Thus the...

I don't understand why you keep saying this. In those couple of hundredths (not billionths) of a second that the ball is in contact with the club, the ball is accelerated from rest to around 170 mph. It attains ALL of this velocity in the time that it is in contact with the club. After the ball...

It's kind of hard to understand what you're trying to say, but I'll take a stab at it. I don't know what you mean by the first sentence at all, but as for the other parts of your post: Yes, the ball requires a time interval to reach its final velocity, and yes there is a displacement...

Why don't you reply to any of my responses? I've given you answers to all the questions you are asking, as have others, yet you refuse to acknowledge them. I get the sense that you are more interested in being right than in being correct.
