Question

WHAT IS THE SI UNIT OF RETARDATION

Answer 1

Retardation is also known as Negative Acceleration .

Acceleration is a vector quantity. 

Acceleration is the rate of change of velocity.

a= V-U/t

So units Retardation of are same as units Acceleration 

Units are : m/s²

Answer 2

The S.I. unit of Retardation is m/s².

Explanation:

Acceleration and retardation both are the rate of change of velocity in per unit of time. The direction of the change of velocity helps in differentiating acceleration and retardation. In acceleration, the direction is the same. In retardation, the direction is the opposite.

Retardation is a negative acceleration.

The unit of acceleration and retardation is the same.
