Question

body travelling with decreasing velocity possess​

Answer 1

Answer:

please mark me as brainlist

Explanation:

Retardation means negative acceleration. It is rate of decrease of velocity with time.

So, if a body undergoes retardation, its velocity decreases.

Answer 2

A body traveling with decreasing velocity posses retardation.

A moving body whose velocity is decreasing will have negative acceleration.

We know from the equations of motion that

a = $\frac{v-u}{t}$

where,

a = acceleration

v = final velocity

u = initial velocity

t = time taken

So when a body has a decreasing velocity, its final velocity will be less than its initial velocity and from the formula, we can see that the values of acceleration will be negative.

Therefore a body traveling with decreasing velocity possess retardation.
