Question

Which is the correct difference between speed and velocity? 

Speed is vector quantity but velocity is scalar quantity

Speed is never zero or negative for a moving body but velocity may be

Speed does not depend upon the path followed by the body but velocity depends

Speed is rate of change of displacement but velocity is rate of change of distance

​

Answer 1

Answer:

Which is the correct difference between speed and velocity? 

Ans - The average speed is the distance (a scalar quantity) per time ratio. Speed is ignorant of direction. On the other hand, velocity is a vector quantity; it is direction-aware. Velocity is the rate at which the position changes.

Speed is never zero or negative for a moving body but velocity may be

ans Speed is a scalar quantity – it is the rate of change in the distance travelled by an object, while velocity is a vector quantity – it is the speed of an object in a particular direction.
