Question

differentiate between speed and velocity. ​

Answer 1

Explanation:

Speed :

(i) Speed is defined as the distance travelled by the body per unit time.

(ii) Speed = distance travelled / timetaken

(iii) Speed is always positive.

Velocity :

(i) Velocity of a moving body is defined as is rate of change of its position with time in a particular direction

(ii) Velocity = displacement/timetaken.

(iii) Velocity is a vector quantity.

(iv) Velocity can be negative.

Answer 2

Answer:

speed is defined as the distance travelled by the body pr unit time .speed= distance travelled/time taken

speed is always positive.

velocity of a moving body is defined as is rate of change of its position with time in a particular direction

velocity = displacement/time taken

velocity is a vector quantity

velocity can be negative
