AI Thread Summary
The discussion explores the theoretical possibility of objects moving with complex and infinite velocities, questioning the nature of velocity functions. It suggests that while certain mathematical models can describe undefined or indeterminate velocities, they do not reflect physical reality, as nature tends to avoid divergences. The consensus is that while some theoretical motions may exist mathematically, they cannot occur in the physical universe due to the speed limit set by the speed of light. Additionally, the velocity of any object must remain a real number, and the concept of an object existing in two places simultaneously due to infinite velocity is deemed impossible. Overall, the conversation emphasizes the distinction between mathematical theory and physical feasibility.

I know some people might think this topic is stupid but I am asking about it anyway.
Can any object real or theoretical move with a function x(t) where:
1_ x'(t) is undefined at all points
2_ x'(t) is an indeterminate form at one point
3_ x'(t) is defined at some points but undefined in others
4_ x'(t) have range of complex numbers
5_x'(t) approaches infinity
So can theoretical objects move with theoretical motion with such crazy velocities exists? if the velocity is infinity will an object exist in two places at the same time? can any real astronomic object move with such velocities because of effects of wormholes or black holes? Is it physically impossible within any universe for such motions to exist. If it isn't physically impossible is there a mathematical way to describe such motions?
I know I am asking about stupid stuff but it is just for curiosity.
Thanks for replying.
 
Physics news on Phys.org
The velocity is a smooth function F.A.P.P. (for all practical purposes) The mentioned artifacts can exist in limiting cases of physical toy models. They are not physical reality and never will be. Nature doesn't like divergences.
There are mathematical ways to describe such functions, but for these you need a deeper understanding of the types of derivatives that exist and the theory of measures.
 
I try to answer your questions:

Yes, it can. Eg. Brownian motion,

2_ x'(t) is an indeterminate form at one point
It cannot. Physics is not mathematics

3_ x'(t) is defined at some points but undefined in others
May be.

4_ x'(t) have range of complex numbers
Speed of the object is always real.

5_x'(t) approaches infinity
No, the speed limit of any object is c. It cannot be infinity.

So can theoretical objects move with theoretical motion with such crazy velocities exists? if the velocity is infinity will an object exist in two places at the same time? can any real astronomic object move with such velocities because of effects of wormholes or black holes? Is it physically impossible within any universe for such motions to exist. If it isn't physically impossible is there a mathematical way to describe such motions?

What about if x'(t) is not continuous?
 
Thread 'Is 'Velocity of Transport' a Recognized Term in English Mechanics Literature?'
Here are two fragments from Banach's monograph in Mechanics I have never seen the term <<velocity of transport>> in English texts. Actually I have never seen this term being named somehow in English. This term has a name in Russian books. I looked through the original Banach's text in Polish and there is a Polish name for this term. It is a little bit surprising that the Polish name differs from the Russian one and also differs from this English translation. My question is: Is there...
I know that mass does not affect the acceleration in a simple pendulum undergoing SHM, but how does the mass on the spring that makes up the elastic pendulum affect its acceleration? Certainly, there must be a change due to the displacement from equilibrium caused by each differing mass? I am talking about finding the acceleration at a specific time on each trial with different masses and comparing them. How would they compare and why?
