In Rowing, displacement, weight, leverage, inertia, hell all of them... Leverage is the key on pulling on an oar, and moment is leverage.

Not sure I understand your question...especially the list of things.

Anyway moment in sports is called leverage. The idea is that fD = Fd; where a small force (f) over a large distance (D) can exactly offset a large force (F) over a short distance (d). This is exactly the thing at work when dad (D) offsets daughter (d) by sitting her way out on the end of a balanced teeter totter while he sits on the other end, but in close to the fulcrum.

As a wrestler in college, I was always concerned with leverage. Hold my oppoenent in the wrong place and he could throw me; hold him in the right place and I'd throw him.

Dealing with force and distance, and how they balance (or not), we need to consider them in all their aspects, which means distance, displacement, vectors, etc. as you listed. For example:

Distance is the moment arm.

Displacement, the movement of a volume of something (e.g., water), allows us to find buoyancy and measure body fat content.

Vectors are used to show the direction of acceleration, speed, and force.

Scalars are nothing but the point values of something, like speed.

Weight is just a force.

Mass is just a measure of force divided by acceleration.

Friction, is one way force is created.

Inertia is simply the resistance of a mass to change in velocity.

Gravity is a force that acts on mass (like the wrestler).

Equilibrium is that balanced teeter totter.

Stability is just the lack of change in one or more of the other characteristics.

There is a lot of movement in any sport. All these principles you talk about are taught in kinetics and statics which is nothing but the study of motion and stability. I feel i have suggested the answer.
