What happens if an real property object meets an unstoppable force is a popular motion on the internet. Of run, relativity intelligibly tells us that there is no such thing as an immovable object. hera ‘s why. If you pick any purportedly immovable object, or good something like your house or the Earth, I can make it move. All I need to do is start moving proportional to it. For example, I might ride a rocket. And on the spur of the moment, from my perspective, I ‘m not moving, and the Earth sails by outside.
The laws of physics make no preference for inertial inning of reference, then from my position here, I do not stir, and yet it ‘s clear the real property aim moves. so because of relativity, immovable objects can not be, but what I think people normally mean by real property object is something that if it ‘s not go, you ca n’t make it start moving by pushing on it, so not an immovable object but an un-acceleratable one.
Using Newton ‘s irregular law, we know that an object ‘s acceleration is peer to the total force on it divided by its mass, though you ‘ve probably seen this as F equals MA. So an un-acceleratable object would be an object with countless mass, an object thus massive that no count how big the sum force F is, when you divide F by M, you constantly get zero.
Of course, as we ‘ve said, not being able to accelerate an object does n’t necessarily mean that the object is n’t moving. It just means that you ca n’t directly change its speed. If it ‘s not moving, then it ‘ll stay not moving, and if it ‘s moving at 100 miles an hour, then it will stay moving at 100 miles an hour.
So what about an unstoppable push ? Well, all the fundamental forces in nature are actually caused by particles, like photons, or gluons, or gravitons, that interact with an object and change its momentum. The only way to not be affected by a force is to not interact with it at all, like how electrons do n’t interact with gluons, so they are n’t subject to the hard nuclear violence. even light up itself is an unstoppable coerce. Every photon that hits your body changes your momentum a bantam fiddling snatch, and there ‘s nothing you can do about it other than avoid light raw or become guileless.
So all forces are already unstoppable, but my depression is that the phrase unstoppable effect is n’t actually meant to imply anything about forces like electromagnetism or graveness, but rather something that you can not stop from barreling down on you — that is, an object whose speed can not be changed by pushing on it. so if by an unstoppable coerce we mean an aim moving at a speed that can never be changed, then that means the object can not accelerate.
But wait a second base. This sounds familiar. Recalling what we learned earlier, an unstoppable force must be an un-acceleratable object, and that means that an unstoppable effect and an real property aim are in truth just the same, viewed from different mention frames.
now, since space mass requires countless energy, we do n’t know of anything in the universe that behaves like this, not the least because it would mechanically be a blacken hole so boastfully that everything in the universe would already be inside of it.
But what if we ignored gravity and imagined there were an un-acceleratable object ? Well, beginning it would be an space reference of complimentary office and would allow us to live in a 100 % happy utopian club and break the second law of thermodynamics and credibly create portals and meter locomotion excessively. You can do a draw with space energy.
But more importantly, if two of these infinitely massive, un-acceleratable objects were moving towards each other and collided, then, since by definition it ‘s not possible for the speed of either of them to change, the only hypothesis is that they must pass right through each other with no effect on each other at all.
