Question

if our body moves with uniform velocity then what is it acceleration positive negative or zero

Answer 1

acceleration will b 0
we know v-u/t=a (where v is the final velocity n u is the initial velocity)
now when in uniform velocity v=u
so acc. is 0

Answer 2

as we all know that v-u\t=a
where v=final velocity
u=initial velocity
t=time
so, if our body moves with uniform velocity then acceleration is positive and zero.
HOPE It WILL HELP YOU
