The main difference between Speed and Velocity: Speed and velocity are fundamental concepts in physics that describe motion, yet they are distinctly different. Mastering this difference is essential for
Speed vs Velocity — Comparison Table
| Basis | Speed | Velocity |
|---|---|---|
| Definition | Distance covered per unit time | Displacement covered per unit time |
| Nature | Scalar quantity (only magnitude) | Vector quantity (magnitude and direction) |
| Formula | Speed = Distance / Time | Velocity = Displacement / Time |
| Can be zero | No, always positive | Yes, if object returns to starting point |
| Example | Car traveling at 60 km/h | Car traveling at 60 km/h North |
Key Points
- Speed is scalar (only magnitude); velocity is vector (magnitude + direction)
- Speed uses total distance; velocity uses displacement (straight-line distance)
- An object can have high speed but zero velocity if it returns to its starting point
- Velocity can be negative or zero; speed is always positive or zero
