SPEED

●Speed of a body is the distance travelled by it for unit time .

● The speed of an object can be calculated by dividing the distance travelled by the time taken to travel distance.

● Speed is a scalar quantity.

VELOCITY

● velocity of a body is the distance travelled by it per unit time in a given direction.

● Thee SI unit of velocity is same as that of speed namely metres per second .

● velocity is a vector quantity .

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

Speed is a scalar quantity that has magnitude but no fixed direction. Velocity is a vector quantity that has both magnitude and direction. Speed is always positive . Velocity can be negative, positive, or O.
