Briefly explain length contraction and one common misconception about it.

## Length Contraction Length contraction is a consequence of special relativity where objects moving relative to an observer appear shortened along their direction of motion. The faster the object moves, the more contracted it becomes, according to the formula: L = L₀√(1 - v²/c²) where L is the contracted length, L₀ is the rest length, v is velocity, and c is the speed of light. ## Common Misconception **The misconception**: Length contraction is a physical compression or distortion of the object itself, like squeezing it. **The reality**: Length contraction is about measurements in different reference frames, not a physical force deforming the object. The object doesn't "feel" compressed—in its own rest frame, it remains perfectly normal. The contraction only appears when measured from a reference frame where the object is moving. It's a property of spacetime geometry, not mechanical stress.
