The main difference between Speed and Acceleration: Speed and acceleration are distinct kinematic quantities, essential for CBSE Class 9 Physics. Understanding their differences clarifies motion analysis and
Speed vs Acceleration — Comparison Table
| Basis | Speed | Acceleration |
|---|---|---|
| Definition | Distance covered per unit time | Change in velocity per unit time |
| Nature | Scalar quantity | Vector quantity |
| Measurement | Only magnitude | Magnitude and direction |
| Unit | m/s | m/s² |
| Zero value | Zero when stationary | Zero at constant speed |
Key Points
- Speed measures how fast; acceleration measures how fast speed changes
- Constant speed means zero acceleration
- Acceleration includes change in speed or direction or both
- Braking provides negative acceleration (deceleration)
