Question

distinguish between speed and velocity​

Answer 1

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.).

Answer 2

SPEED

Speed is the distance traveled or the rate of change of distance. It is a scalar quantity.

Can be expressed in terms of;

meters/secondkm/hour

VELOCITY

Velocity includes speed and direction both. It can be defined as the speed in a particular direction or distance traveled by an object in a specific direction per unit time. Where as, acceleration is the rate of speed on which the object travels.

Basically velocity is a vector quantity and is specified in m/s (meters/second).

Equation is;

Velocity = Change in distance / Time traveled

DIFFERENCE BETWEEN SPEED AND VELOCITY

Speed is the distance traveled by an object where as, velocity is distance traveled by an object per unit time in a particular direction.Speed is a scalar quantity where as velocity is a vector quantity.Speed can be expressed in terms of meter/second and km/hour where as, velocity is expressed in terms of meters/ second.Velocity can be calculated by;

velocity = change in distance/time taken

Speed can be calculated by;

speed = distance traveled /time taken

Speed just includes speed or distance traveled ignoring direction where as, velocity is the distance traveled in a particular direction
