Question

write relation between speed and magnitude of velocity .
​

Answer 1

Answer:

Speed is a scalar quantity and velocity is a vector quantity. Velocity, being a vector, has both a magnitude and a direction. The magnitude of the velocity vector is the instantaneous speed of the object.So while the magnitude of the velocity vector may be constant, the direction of the velocity vector is changing.

Answer 2

Answer:

Speed is a scalar quantity and velocity is a vector quantity. Velocity, being a vector, has both a magnitude and a direction. The magnitude of the velocity vector is the instantaneous speed of the object. The direction of the velocity vector is directed in the same direction that the object moves.
