Difference between Speed and Velocity

Q. Difference between Speed and Velocity.

Top Answer

Solution:
Difference between Speed and Velocity.

Speed	Velocity
1. The rate at which an object covers distance.	1. The rate at which an object changes its position in a specific direction.
2. Speed is a scalar quantity (only has magnitude, no direction).	2. Velocity is a vector quantity (has both magnitude and direction).
3. Speed is always considered as positive quantity.	3. Velocity can either be positive or negative or even zero.
4. Its magnitude is either greater than or equal to that of velocity.	4. Its magnitude is either equal to or less than that of speed.
5. Calculated as Speed = Distance/Time	5. Calculated as Velocity = Displacement/Time
6. Example – A car moving at 60 kilometers per hour.	6. A car moving at 60 kilometers per hour north.
7. Remains constant even if the direction changes, as long as the rate of motion remains the same.	7. Changes if either the speed or the direction of motion changes.
