Clarifying the Relationship between A and B

[Noxide]

If I want to find A relative to B, what am I really looking for?

Am I assuming that A is fixed at the origin and looking at B's motion compared to A, or the converse?

Could someone please clarify this for me.

Also, does the same thing apply to with respect to?

A with respect to B?
This means that B is fixed and we're looking for A compared to B right?

Just a little clarification needed!

Thanks

What are A and B? The way you're phrasing your questions, it sounds like A and B are particles, and in that case finding A with respect to, or relative to, B, makes no sense. It's like asking how to calculate your chair relative to your keyboard.

What I'm guessing you're actually asking is how to find the velocity of A relative to (or with respect to) B. In that case, what you would be looking for is the velocity of A in a reference frame where B is fixed at the origin. In Newtonian physics, this is just the velocity of A minus the velocity of B.

If you wanted to find, say, the electrical potential of B with respect to (or relative to) A, then it would be the potential of B minus the potential of A.

for your question! The relationship between A and B can vary depending on the context. If you are looking for A relative to B, you are essentially trying to determine the position or movement of A in relation to B. This could mean that A is fixed at the origin and you are observing B's motion in relation to it, or it could mean that B is fixed and you are observing A's motion in relation to it. It all depends on the specific scenario and what you are trying to analyze.

The same concept applies to "with respect to." If you are looking at A with respect to B, you are essentially looking at how A is positioned or moving in relation to B. This could mean that B is fixed and you are observing A's motion in relation to it, or it could mean that A is fixed and you are observing B's motion in relation to it.

In summary, the relationship between A and B is determined by the context and what you are trying to analyze. It could involve observing the motion of one object in relation to the other, or it could involve comparing the positions of both objects. I hope this helps clarify the concept for you.
