Velocity vs Speed
Speed: Speed is defined as the distance travelled by an object per unit time. It is the magnitude of velocity and is a scalar quantity. Speed does not take into account the direction of motion.
Velocity: Velocity is defined as the displacement of an object per unit time. It is the rate of change of displacement and is a vector quantity. Velocity takes into account the direction of motion.
Difference between Velocity and Speed
1. Definition: Speed is the distance travelled per unit time, while velocity is the displacement per unit time.
2. Scalar and Vector Quantity: Speed is a scalar quantity while velocity is a vector quantity.
3. Direction: Speed does not take into account the direction of motion, while velocity does.
4. Magnitude: Speed is the magnitude of velocity.
5. Formula: Speed is calculated by dividing the distance travelled by the time taken, while the velocity is calculated by dividing the displacement by time taken.
6. Representation: Speed is represented by 's', while velocity is represented by 'v'.
Conclusion
In conclusion, the main difference between velocity and speed is that velocity is a vector quantity, while speed is a scalar quantity. Velocity takes into account the direction of motion, while speed does not.
