Hello there. In class, our teacher solved one question and asked us what did we wrong specifically in the solution because there were two sets of them. Two spaceships are moving through +x and -x and there is a distance L between them. From one observer which is stationary in the line of L/2...
Hello. I started to work on pedrotti optics book (2nd edition) and i got confused about what is relativistic mass and why we use it rather than kinetic energy (1/2mc^2)?
Also in the beginning of these explanations there is one equation i barely understand nothing out of it. Could you please...
Let me clarify my question in this way, when i use a coordinate transformation lastly i put it in this way x' = xcos(theta) - tsin(theta) and also for t' = tcos(theta) - xsin(theta)
but in the beginning of this equation i could not see how the light has the same velocity in every inertial...
I am trying to understand why maxwell equations are correct in any reference frames? While i started to understand of his laws of physics a bit i could not imagine why he uses hyperbolic functions such as coshw instead of spherical ones in position and time relation between moving frames...
Hello there, i have a confusion about the force concept itself because when i look dimensionaly i see that N = kg.m/s^2 but i do not understand how the force interacts with time. Is it just about where the object and what is the net force on it due to a reference frame at that moment ? Or...
Hello there, i have a question that confuses me a lot. Is there a difference between the way that we think about time in many classical physics concepts as if it goes to a negative number. For example, we have dv/dt and we can be sure if velocity increases with respect to time and respect to our...
