Difference Between Distance and Displacement
Distance and displacement are two ways to measure how far an object has moved. Distance measures the total path length traveled, while displacement measures the shortest straight-line distance between start and end points.
Distance vs Displacement — Comparison Table
| Aspect | Distance | Displacement |
|---|---|---|
| Definition | Total path length traveled | Shortest distance between initial and final position |
| Type | Scalar | Vector |
| Value | Always ≥ 0 | Can be positive, negative, or zero |
| Path Dependent | Yes | No |
| SI Unit | Meter (m) | Meter (m) |
| For circular trip | Equal to circumference | Zero |
Key Points to Remember
Distance ≥ |Displacement| for any path
For straight-line motion in one direction, Distance = |Displacement|
Displacement depends only on initial and final positions
Distance is always non-negative
Exam Relevance
This topic falls under Kinematics in Physics for both JEE and NEET. Questions on the difference between distance and displacement appear frequently in competitive exams, both as direct MCQs and as part of numerical/assertion-reason problems.
