Special Relativity-Assignment Questions and Answers Latest Version (2024/2025) Already Passed What is the key principle behind Einstein’s theory of special relativity? The laws of physics are the same for all observers in inertial frames of reference. How does time dilation affect a moving clock compared to a stationary clock? A moving clock runs slower compared to a stationary clock when observed from the stationary frame of reference. What happens to the length of an object moving at high speed relative to an observer? The length of the object contracts in the direction of motion as its speed approaches the speed of light. What is the formula for time dilation in special relativity? Δt' = Δt / √(1 - v2/c2), where Δt' is the dilated time, Δt is the proper time, v is the relative velocity, and c is the speed of light. 2 What is the relativistic mass of an object moving at a speed close to the speed of light? The relativistic mass increases as the object’s speed approaches the speed of light. What is the effect of special relativity on the concept of simultaneity? Simultaneous events in one frame of reference may not be simultaneous in another frame of reference moving relative to the first. What is the equation for relativistic kinetic energy? K.E. = (γ - 1)mc2, where γ is the Lorentz factor, m is the rest mass, and c is the speed of light. How does the speed of light behave according to special relativity? The speed of light is constant in all inertial frames of reference, regardless of the motion of the source or observer. What happens to the mass of an object as it approaches the speed of light? The object's relativistic mass increases and approaches infinity as its speed approaches the speed of light. 3 What does the Lorentz factor (γ) represent in special relativity? The Lorentz factor represents the time dilation and length contraction effects and is given by γ = 1 / √(1 - v2/c2). What happens to the energy of a particle as its speed increases? As a particle's speed approaches the speed of light, its total energy increases significantly. How is the energy-mass equivalence formula related to special relativity? The energy-mass equivalence formula, E = mc2, shows that energy and mass are interchangeable and that a small amount of mass can be converted into a large amount of energy. How do moving observers measure the speed of light? All observers, regardless of their motion
