Question

give the difference between speed and velocity

Answer 1

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

Answer 2

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