Lorentz Factor Formula:
From: | To: |
The Lorentz factor (γ) is a quantity that appears in several equations in special relativity. It describes how much time, length, and relativistic mass change for an object while that object is moving relative to an observer.
The calculator uses the Lorentz factor formula:
Where:
Explanation: The factor approaches infinity as velocity approaches the speed of light, and equals 1 when the velocity is zero.
Details: The Lorentz factor is crucial in special relativity for calculating time dilation, length contraction, and relativistic mass increase. It's fundamental to understanding high-velocity physics.
Tips: Enter velocity in m/s and speed of light in m/s. Velocity must be less than the speed of light. The default value for speed of light is set to 299,792,458 m/s.
Q1: What happens when v approaches c?
A: As velocity approaches the speed of light, the Lorentz factor approaches infinity, meaning time dilation and length contraction effects become extreme.
Q2: What is the range of possible gamma values?
A: γ ranges from 1 (at rest) to approaching infinity (as v approaches c). For v > c, the value becomes imaginary, which is not physically meaningful in special relativity.
Q3: How is gamma used in time dilation?
A: Time dilation is calculated as Δt = γ × Δt₀, where Δt₀ is the proper time interval in the rest frame.
Q4: What are practical applications of the Lorentz factor?
A: Used in particle accelerators, GPS satellite corrections, and any system where relativistic effects are significant at high velocities.
Q5: Why can't anything travel faster than light?
A: As v approaches c, γ approaches infinity, requiring infinite energy to accelerate further, making faster-than-light travel impossible according to special relativity.
