What Is Delta Δ and Why Do We Use It?

[-Physician]

What is delta $Δ$, where and why do we use it ?

Sounds like homework. What have you found in your Google/Wiki search?

I haven't actually searched, I thought I would get a better answer here, it's not homework, it's my own question.

Hm, I see it is change , thanks, so like $v$ is velocity but $Δv=v_f-v_0$, but what would be $Δp$ (delta momentum), $p_1-p_0$?

Yes.

it's a greek letter and you can use it for whatever you want.
