Question

Give S.I. unit of
(a) velocity
(b) retardation

Answer 1

velocity-m/s

retardation-(-m/s²)

Answer 2

a) Velocity

We know that the formula of velocity is derived as displacement divided by time.

So, the unit of velocity or it can be said that SI unit of the physics term velocity is metre per second (m/s)

b) Retardation

Retardation can be written as velocity which is divided by time.

So, the SI unit of the physics term retardation will be metre per second square (m/s^2)
