Question

difference between instantaneous speed and instantaneous velocity?

Answer 1

INSTANTANEOUS SPEED MEANS THE MAGNITUDE OF VELOCITY AT ANY INSTANT OF TIME. IT HAS ONLY MAGNITUDE

BUT INSTANTANEOUS VELOCITY MEANS VELOCITY AT ANY INSTANT OF TIME I.E. IT HAS BOTH MAGNITUDE AS WELL AS DIRECTION

Answer 2

Instantaneous speed is the magnitude of instantaneous velocity. Instantaneous velocity is a vector. Instantaneous speed is the magnitude of instantaneous velocity. It has the same value but is not a vector so it has no direction.
