When a body is thrown upward
initial velocity=u and final velocity =0
when a body is dropped from a height
initial vel.=0 and final vel.=v
when a body is thrown from a height (downward)
initial vel.=u and final vel.=0

Do you have a question as you appear to have forgotten to copy the entirety of your work.

No sir actually its just a doubt

I want to know that what I have written is correct or not. Please help me

At its apex its velocity is 0 - is that what you mean by "final velocity?"

Generally true, unless something else acts on the body.

No, why would the final velocity be 0? (Unless you're thinking of a case where the object hits the ground and hence comes to a stop.)
