Question

what is the difference between speed and velocity​

Answer 1

speed is a scalar quantity but velocity is a vector quantity.
speed = distance/time
velocity = displacement/time

Answer 2

The short answer is thatvelocity is the speed with a direction, while speeddoes not have a direction.Speed is a scalar quantity—it is the magnitude of the velocity. Speed is measured in units of distance divided by time (e.g., miles per hour, feet per second, meters per second, etc.).

OR

this is major difference between Speed and Velocity. Though both are calculated using the same units (km/h, m/s, mph, etc.), the two are different in that one is described using numerical values alone (i.e. a scalar quantity) whereas the other describes both magnitude and direction (a vector quantity).

OR

Velocity is a vector quantity and has both magnitude and direction. Speed and velocityboth represent a way to measure the change in position of an object relative to time. In fact, for a straight line motion, the speed and velocityof an object are the same (since distance and displacement will be the same).
