Question

how to calculate uniform retardation magnitude​

Answer 1

Answer:

So formula will be the same as that of acceleration. Where v = final velocity, u= initial velocity & t= time taken to change the velocities. So in case of v<u; you are going to get a negative value of acceleration which is also called retardation/de-acceleration/deceleration.

Answer 2

Answer:

Retardation means negative acceleration. This happens every time when the velocity of an object decreases.

So obviously we can say that when final velocity is less than initial velocity; we are going to have negative acceleration.

So formula will be the same as that of acceleration.

As acceleration can be defined as the rate of change of velocity i.e. mathematically: a= (v-u)/t

Where v = final velocity, u= initial velocity & t= time taken to change the velocities.

So in case of v<u; you are going to get a negative value of acceleration which is also called retardation/de-acceleration/deceleration.
