Question

difine speed and velocity​

Answer 1

Answer:

The amount of distance covered in a unit time by a body is its speed, and the amount of displacement that took place along with the direction of the body, in unit time is called velocity.

Answer 2

1. Speed: It is defined as the distance travelled by an object in per unit time.

Speed= distance travelled / total time taken

V=s/t =m/s unit = meter/second

Speed is a scalar quantity.

2. Velocity: It is defined as the displacement travelled per unit time.

Velocity=displacement travelled/time taken

Unit=m/s

It is a vector quantity
