Discussion Overview

The discussion revolves around the concepts of friction related to different geometric shapes (cone, wedge, sphere) and touches on broader topics of speed, time, and relativity. The scope includes conceptual understanding and some exploratory reasoning regarding physics principles.

Discussion Character

  • Exploratory, Conceptual clarification, Debate/contested

Main Points Raised

  • One participant inquires about which shape (cone, wedge, or sphere) has less friction and mentions a need for a material that can withstand extreme temperatures.
  • Another participant corrects the first by stating that the concept of time dilation is from Einstein's theory of Special Relativity, not Newton's, and emphasizes that exceeding the speed of light is impossible.
  • A participant questions the idea of "breaking the speed of time," indicating a misunderstanding of time as a dimension rather than a speed.
  • Another response clarifies that time is a measure that helps determine speed and discusses the relativity of time dilation, noting that two clocks in the same reference frame will agree on time passage.
  • A later reply reflects on the need for further research and expresses confusion about the concept of time slowing down significantly.

Areas of Agreement / Disagreement

Participants do not reach a consensus on the original question about friction, and there are multiple competing views regarding the nature of time and speed. The discussion remains unresolved on these points.

Contextual Notes

Limitations include a lack of clarity on the definitions of friction in relation to the shapes mentioned, as well as unresolved assumptions about the relationship between speed and time.

Well hi. I am in 7th grade and I am learning physics. Me and my friend saw a vid on 1 of Newton's theroys. It was "time goes slower while moving faster", if i recalled right. and me and my friend wanted to go past the speed of light to break the time barrier and make time stop from Newton's work and theroy. So I am stuck on 1 question which has less friction a cone, a wedge, or a sphere? and i need to know of a matirial that can stand extreme temps. thanks in advance.

First, that is actually from Einstein's theory of Special Relativity, not Newton's. Second, you cannot exceed the speed of light, and actually, you couldn't even come remotely close to it with any normal technology. Even if you had sufficient energy to get close to the speed of light, it can never be exceeded - this is one of the consequences of relativity. It would require infinite energy to even reach the speed of light, in fact. As far as drag is concerned, the drag of shapes is velocity dependent, although none of the listed shapes are exactly optimal.
 
so we can't break the speed of light so is it possible 2 break the speed of time and srry i forgot it was Einstein who did that

There's no such thing as 'the speed of time'. Time is something that aids us in determining speed. Time dilation does indeed occur with increasing speed, but remember that it has to be relative to something else. Two clocks traveling together at whatever speed will agree, while one in a different reference frame will notice a change of pace.

edit: So why won't the dictionary link let me capitalize 'time' in my third sentence?
 
i need to plan more things out and reaserch a lot more

anyways i didnt know there was no such thing as speed of time what i was referring 2 is that the speed of which things are moving slows down so much it will stop or at least slow down so much u can barley notice it.
