Question

Dimensional formula for averagevelocity

Answer 1

Dimensional formula for Avg. velocity is
Velocity= Displacement / Time
= L / T
= LT^-1
Hence, (M^0 L^1 T^-1)

Answer 2

average velocity : it is the ratio of total displacement by total time taken.

e.g., $v_{av}=\frac{\text{total displacement}}{\text{total time taken}}$

we know, dimension of displacement = dimension of length = [L]

dimension of time = [T]

so, dimension of average velocity = [L]/[T]
= [LT-¹]
