When the velocity is constant, can the average velocity over any time interval differ from instantaneous velocity at any instant ? If so, give an example, If not, explain why.

Explanation

No. Here velocity is constant.
`therefore` Average velocity over any time interval is same and the instantaneous velocity at any instant is same.
Ex : Let us consider a car moves on a straight road with constant velocity say 10 m/s.
1) Now let the distance covered (AB) by the car in 1s = 10m.

2) Distance covered in 2s (AC) = 20 m.
Average velocity from A to C is `(20m)/(2s)=10m//s`.
3) Instantaneous velocity at A or B or C at any point = 10m/s.
