Question

speed and velocity.

Answer 1

- speed is the distance covered in unit time
s=distance/time
-velocity is the displacement covered in unit time
v =dispacemet/time
speed is scalar quantity such as a person is moving with speed of 2m/s this is speed but if we say a person is moving with velocity of 2m/s toward north this is velocity because it is vector so it is necessary to mention direction of it .

Answer 2

speed is the distance covered in a unit time. speed=distance by time. it is scalar qauntity.
velocity is the rate of displacement. vel
