Final answer:
The Lorentz Factor (γ) becomes 1 when the relative speed is zero, indicating no time dilation or length contraction.
Step-by-step explanation:
The Lorentz Factor, denoted by the symbol γ (gamma), is a mathematical term used in special relativity to describe the time dilation and length contraction effects that occur at high velocities. When the relative speed is zero (u = 0), the Lorentz Factor (γ) becomes 1. This means that there is no time dilation or length contraction observed. In other words, the object's time and length appear the same for observers in different inertial frames.
