Answers below are taken from the article’s stored facts, so they match what the student read.

1. What is Lorentz contraction?Lorentz contraction is when an object moving very fast looks shorter in the direction it's moving, but it hasn't actually squished.
2. Why does an object look shorter when it moves fast?Because the speed of light stays the same for everyone, the measurements of space change, making the moving object's length appear compressed.

Lorentz Factor (γ): A factor that quantifies the degree of relativistic effects, increasing with velocity relative to the speed of light.
Proper Length (L₀): The length of an object measured in its own rest frame, where it is stationary.
Spacetime: A unified four-dimensional continuum combining three dimensions of space and one dimension of time.
