Special Relativity - 5 easy questions | German Physics | Minkowski Diagram

Struggling with special relativity? Test your understanding with these 5 easy yet insightful questions! We cover key concepts like charge density in different frames, why simultaneity is not absolute, length contraction of a moving train, causality & event order reversal, and how the speed of light remains invariant. Learn to use Minkowski spacetime diagram to communicate important idea – perfect for university students. These are question in German taught in premier European Universities. Timestamps: 0:00 Introduction and questions 0:36 Question 1 – Charge density changes 1:22 Question 2 – Simultaneity is relative 2:42 Question 3 – Length contraction example 3:32 Question 4 – Causality & reversed event order (Minkowski diagram) 6:37 Question 5 – Speed of light in another frame Great for physics undergrads preparing for exams or just wanting to really "get" Lorentz transformations and inertial frames. If this helped, like 👍, subscribe for more physics explained simply, and comment which question was trickiest for you! The questions are: Q1: Lorentz Transformation: A non-conducting sphere has charge density 𝜌. Can the charge density be changed by the Lorentz transformation to different frame of reference? Q2: Simultaneity: A physicist tells you: "Simultaneity is not absolute." What does he mean by that? Q3: Length Contraction: A 100 m long train moves at relativistic speed. It travels through an 80 m long tunnel. An observer in the tunnel's rest frame determines that the train fits exactly into the tunnel at a given time. What speed is the train traveling in units of the speed of light, c? Q4: Causality: In the reference frame K, two events (event1, event2) occur at the same location, at times t1 and t2, such that t1 less than t2, i.e., event1 occurs before event2 in frame K. An observer moves with velocity v in the +x direction. For the observer, can event2 occurs before event1? Q5: Speed of Light: You are traveling in your spaceship at half the speed of light, c, towards an enemy planet. You fire your laser weapon and see the light pulse traveling towards the planet at the speed of light. At what speed, v, do your opponents on the planet see the light pulses approaching them? #SpecialRelativity #MinkowskiDiagram #PhysicsTutorial #LengthContraction #RelativityQuestions #LorentzTransformation #GermanPhysics Channel: Tutor Mahesh – Making physics clear and fun!
