Question

Difference between Speed and Velocity...

Answer 1

Speed => It is the distance covered by the body per unit time. It is scaler quantity. It gives an idea about rapidity of an motion of body.

Velocity =>It is the displacement of the body per unit time. It is a vector quantity. It gives an idea about rapidity as well as positon of body in motion.

Answer 2

Speed.......

1 ) Distance travelled by a moving body per unit time is called speed .

2 ) It is a scalar quantity .

3 ) Average speed of a moving body cannot be zero .

Vector........

1 ) Distance travelled by a body per unit time in a definite direction is called velocity .

2 ) It is a vector quantity .

3 ) Average velocity of a moving body can be zero .
