from the dictionary:

chord2 ( P ) Pronunciation Key (kôrd, krd)
n.
A straight line connecting the leading and trailing edges of an airfoil.

No Jax;

There are many, many straight line in aviation that are called just
that, and you know it.

You also know that "Chord" is used as a measurement in Airfoil
dimensions. Also used in Sail Trim.

However, that does't answer the question about Sail Trim for Newton's
Law, does it? That is the question that has been posed to you. How do us
"OLD SAILORS" know how to get the most out of sail trim adjusting for
Newton's Law. What do we look for as we adjust;
Halyard tension

Outhaul

Cunningham

Sheet tension

Vang tension

Slot position MAIN/JIB

We know these things affect the speed of the boat. How can we know how
to get the Max Effect? What do we look for?
We know those "Dumd Ass sialing to those Bernoulli postioned tel-tails
are going faster. Help us converts to Newtons Law.
