Thank you. now that's much better. I'm not quite sure why I wrote that, because that's simply not the case. maybe I was a bit upset about your response. That's quite clear that the pressure in the front row is greater than in the back row. This is what I have addressed in the OP. If you had...

Hi Dave It's easy to declare any piece of writing as ungrounded; but as much as a post is needed to be written in a proper and scientific manner, it is expected that such declarations, on their own, be based on facts, logic, and more importantly, be specific as much as possible. It's just like...

Your manner of speaking is not only unscientific, but also quite unfriendly. This forum as suggests in the opening pages, is a place to communicate ideas and not a class room in which EVO is a professor. You haven't got the gist of what I am talking about in the OP, and still, giving me all...

The main part of what you have quoted me is a restatement of the third law of Newton: " When one body exerts a force on a second body, the second body simultaneously exerts a force equal in magnitude and opposite in direction on the first body." Wiki. Are saying that it is not correct? What I...

I quite agree with you on increasing forces as you move forward to the front, but the reason being, as I see it, is that every row contributes to sum total of the force that the next row is receiving and not the friction. In fact, I would have thought that the friction only hampers the transfer...

In physics, sometimes, we try to set aside the non-relevant factors, and only consider the one we are after. So we construct our unique situation. regards.

Could you please elaborate. As we are only considering the effects of the 'pressure', then any other factor like a 'strike' is dismissed. A sudden increase in pressure made by a rush is considered a "strike".

No matter how many people there are in the crowd, if the next one to you is pushing on you with a force of say 1000N, then you are pushing on him with exactly the the same amount of force, i.e. 1000N. As such, both should suffer the same amount of injury.

A simple search would have answered your question. https://www.washingtonpost.com/news/speaking-of-science/wp/2015/09/24/what-can-science-tell-us-about-human-stampedes/ As has been mentioned in the OP, what is being asked here is not the reason of death by being trampled or knocked down; rather...

Would a crowd be able to push so hard to kill an individual? Apart from all political disputes and different reports concerning the recent Hajj pilgrimage incident, I’m a bit curious as to some physical aspects of the incident.Suppose some one million pilgrims are walking towards a particular...

Thank you Dale, I just give it a thought and return.

Interesting question. I think you put it politely. May be what you mean is, better said, why don't I go and stand exactly at the foot of the perpendicular! I am thinking about it.

What made me think of this, is this alleged paradox.http://www.phys.unsw.edu.au/einsteinlight/jw/module4_pole_paradox.htm Maybe you can help me find a valid answer. I will also present my humble solution.(which I have partly done).

Granted. Let's talk about your example first. If you agree that speed involves movement, and movement involves distance, then if there is no change of distance, than there is no movement. Although the movement of the car is tangential, but at the very moment it is, on its path, at the...

Let's forget about acceleration, for the moment. Instead, I use the word speed. what about that? Is it true that at one moment a photon is stationary relative to me.
