Question

distinguish between speed and velocity.?

Answer 1

The short answer is that velocity is the speed with a direction, while speed does 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....

distinguish between speed and velocity?

$\huge\bold\star\red{Answer}$

Speed the distance travelled by a body per unit time.

⠀⠀⠀⠀⠀⠀speed=distance/time

✎it is a scalar quantity

✎it is always positive

✎its SI unit is m/s

Velocity the distance travelled by a body per unit time in given direction.

⠀⠀⠀⠀⠀⠀velocity=displacement/time

✎it is a vector quantity

✎it can be positive, negative and zero

✎its SI unit is m/s
