Do we need to have two objects two have momentum?

Do we need to have two objects two have mometum?
I am just confused. Hope someone helps

No. Any and every object has momentum.

Momentum is basically them same as inertia: on objects tendency to maintain its current motion (or its resistance to changing that motion).

Are there any more specific questions or point-of-confusion that you have?

tx a lot got it, was just confused with the term.
Now 1 more question can we figure out an objects momentum and its inertia?

The two are synonyms, however momentum also means a quantitative value which is the objects mass times its velocity.

p = mv

Inertia is more qualitative, though it is sometimes just equated with mass.

I advise you to NOT mix your non scientific intuition about ideas like "momentum", "inertia" and later "Work" - they have precise mathematical a physical definition which you need to know WELL in order to use these ideas to solving problems.
