This is AN AMAZING course. I´ve never met before such clear but deep ideas on teaching about SR..... The only improvement I can think of would be a similar course in General Relativity: Such course would be AWSOME if taught by this incredible teacher. Thanks for this course from Spain.

If velocity is constant with time for isolated object in inertial frames how are we finding acceleration of two isolated objects in inertial frames can't understand 😶
@shiva10522 жыл бұрын
The idea is that on isolated objects there can not be a real force. Hence as per Newton’s law, the acceleration of the isolated object is zero. A frame in which one really notices zero acceleration for an isolated object is an inertial frame.
@avinashganji69387 жыл бұрын
hai sir will you please explain me once that the point you have said at 28:20 in the above lecture that you had said the both frames s ans s' are intertial frames of references but the relative velocity between the both frames of references does not depend on time . My dought is why it doesnt depend on time.
@shiva10527 жыл бұрын
It has been explained at 21:00. Observers in two inertial frames find an isolated object to move with a velocity which does not depend on time. It means that the relative velocity between the frames is also time independent. Hence an inertial frame can not accelerate in the frame of any other inertial frame.

can any one explain at 20.15 he said velocity of object should be constant and at 24:24 he said object may have acceleration???
@shiva10527 жыл бұрын
At 20:15, the object was assumed to be an isolated one implying that there is no real force on it. Hence in an inertial frame its velocity would be constant. At 24:24, the object being observed need not be isolated, hence there could be a real force acting on it, causing it to accelerate even in an inertial frame.
@sumitkumarshakya30394 жыл бұрын
At 20:15 he is saying that acceleration is not dependent on frame of refference (means when we change frame of reference the acceleration will not change). At 24:24 he is saying let the object be accelerating and the if we switch the frame of refference from non inirtial to an inertial frame or switch from inertial to inertial frame the accleration would be same in all frame of refferences . Which he has proved in last of that topic . Hope this would help you 🙂

Sir i have a question. Why we can't compare the speeds observed from two diffrent frame of refrences?
@shiva10526 жыл бұрын
Your question is not clear. We can always compare speeds observed from two different frames. Only thing they would be different in different frames. The velocities in two different frames would follow standard relative velocity formula. If the speeds are high and are close to speed of light, you must use relativistic formula.

@shiva10524 жыл бұрын
An inertial frame can not accelerate relative to another inertial frame. Of course, in case a real force is applied to a particle, that particle would be found to be accelerating in an inertial frame. In the same fashion, if there is no real force on it, the particle would appear to move with a constant velocity in an inertial frame.

Sir ...can you explain again why we came the idea of ether to eliminate the the difficulties of the different speed of light for different reference frame??I don't understand that part..
@shiva10525 жыл бұрын
The basic issue is that according to electromagnetic theory speed of light is related to fundamental constants. Also according to classical relative velocity formula, the velocity is a frame dependent quantity. Hence if the fundamental constants are not frame dependent, how can speed of light be frame dependent? By introducing the concept of Ether, one could say that it is only if speed of light is measured in Ether frame, will that be related to fundamental constants. Speed of light in any other frame will not bear the relationship with fundamental constants as was derived from electromagnetic theory. Further the concept of ether also helped the scientists of that era in visualizing light as a wave which requires a medium to travel. Because presence of a medium was considered essential for waves to propagate.

Thanks for reply..sir..listen once more...We can just take a reference frame outside the earth (in space) to get the absolute rest condition ...but why we needed to consider a medium such as ether to overcome the problem??Yes,I understand this theory can explain other demand such as propagation of light,let just forget about that .... general theory of relativity sustains as long as we hold the existence of ether medium....but why go to the idea of ether in the first place where we can just claim space as as a reference frame as absolute rest???

@shiva10524 жыл бұрын
The bodies can accelerate in an inertial frame only when there is a real force on them. And this force can arise only as a result of interaction with some other body. The idea of having an isolated body (particle) is that there can not be a real force on that, which ensures that the body is not accelerated. .I hope I have answered your question.

There is one problem when he talks about measuring speed of light in different reference frames. His conclusion is right while i doubt his argument. He argues that different observers in different frames measures speed of light differently because frame is moving too, CORRECT! but then he argues that are the values of permeability and permitivity different in different frames? I find this wrong argument as the observer is NOT measuring the ABSOLUTE speed of light, all he is doing is measuring RELATIVE speed of light from his reference. When he will measure the speed of light (absolute) from a light source in his reference system then he will be actually in a position to compare observed speed of light with maxwell's formulae
