Question

what is retardation? What is the formula of retardation?​

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:

what is retardation?

Retardation is the act or result of delaying; the extent to which anything is retarded or delayed; that which retards or delays.

What is the formula of retardation?

Retardation or deceleration is negative change in velocity per unit time. So, Here, retardation=change in velocity/time(seconds). Retardation= -acceleration

hope this helps you ☺️☺️✌️✌️
