    B Calculating Time taken to reach speed with Time Dilation

    So I've learned about time dilation and how getting close to the speed of light can have affects of time dilation. Looking into a bit more I see that when you are really close to the speed of light, say getting to the point of 99.9999999999% the speed of light, then it starts to become that...

    I Is There Experimental Evidence That Contradicts Time Contraction Predictions?

    I have another question linked to the equations of Lorentz: The Theory of the Special Relativity (SR) of Albert Einstein comes from the equation of Lorentz and we have the following equation on the time t’ in the moving frame: The “space time” (x’, y’, z’, t’) is moving at a speed v measured...

    Speed of a moving object, according to another moving object

    Homework Statement Special Relativity Question. Consider objects 1 and 2 moving in the lab frame; they both start at the origin, and #1 moves with a speed u and #2 moves with a speed v. They both move in straight lines, with an angle θ between their trajectories (again in the lab frame). What...

    I Interactive Minkowski Diagram Tool

    I've made a Interative Minkowski Diagram Tool, http://divykjain.github.io/IMD You can add events, connect events and add world lines. Lorentz transformation for moving frames also present. I've added support for frame velocities equal or greater than light speeds(but the animations are a mess...

    B Einstein relativity is invalid

    Hi, Need your help to unravel the claims made by a poster in my local forum, if it has any merits. I do not have the expertise to evaluate his claims but am hoping if you can give me a few points on his line of reasoning, if it is faulty or not. I have a general background in undergraduate...

    Homework Help -- Relative Velocity

    <Moderator note: moved from technical forums, so no template> Problem: Two trains (A and B) are moving along parallel tracks at different speeds. A person sitting on train A looks out the window and sees two things happen: a firecracker explodes right outside his window, and, exactly 1.0...

    I Use Lorentz Force to Find Magnetic Field Components

    So I am constructing an analogy between the self replicating fracturing effect on thin films and the path of a charged particle. (Qualitatively, several cracks have similar shapes to charged particle motion) I won't go into the details of the fracture mechanics, so I will only use E+M...

    Observing from Earth the clock in a spaceship

    Homework Statement A spaceship leaves Earth at time ##t=0## with constant speed ##u##. Its clock is synchronized with the terrestrial one. At time T an earthling reads with an optical telescope the clock inside the spaceship. What value does he read? Homework Equations Lorentz equations. The...

    Does the Lorentz equation preserve causality?

    Homework Statement Observer S' moves at a speed u compared to observer S in x-direction. Two events happen on the x-axis of S, with the coordinates x1 and x2 at times t1 and t2 measured in S. Let L = x2-x1 and T = t2-t1. a) If the events happen at the same time in S, does the same apply...

    Understanding the Lorentz Equation: Clarifying the Confusion

    I am confused of how to derive the Lorentz equation x = vt+x'/γ...if x' is the distance to an event according to O' and x is the distance to that same event according to O, then shouldn't the last term be x'γ not x'/γ, since x' is already contracted according to O, so to relate it to x, we would...

    Need Help Solving the Lorentz Equation for a Charged Particle?

    Sometime last year, I wrote a textbook on introductory E and M. In one of the chapters, I attempted to solve the Lorentz equation for a charged particle moving in an arbitrary magnetic and electric field, that I'm not so sure about. Is anyone, who has some experience with solving systems of...

    Solve Lorentz Eq for Charged Particle Motion in EM Field

    The motion of a charged particle in an electromagnetic field can be obtained from the Lorentz equation for the force on a particle in such a field. If the electric field vector is E and the magnetic field vector is B, the force on a particle of mass m that carries a charge q and has a velocity...

    Geometrical meaning of Lorentz equation?

    Could we give a geometrical meaning of the Lorentz equation mx´´=e(vxB)+eE...similar to that of gravitation..by considering that e(vxB)+eE comes from a potential..and the electrons are moving in geodesics?..
