That is referred to as the "load" or "force" that needs to be overcome in order to achieve a desired movement or outcome.
To overcome by greater force is often referred to as overpowering or overwhelming the opposition.
Objects that provide resistance are often referred to as obstacles, hindrances, or impediments. These objects can impede progress or hinder movement.
The resistance to a change in velocity is called "inertia". It is related to the mass of an object.
Materials with a resistance of 0 ohms are called superconductors. Superconductors exhibit zero electrical resistance when cooled below a critical temperature, allowing them to conduct electricity with no loss of energy.
A scale that measures body weight is simply called a "weight scale" or "bathroom scale."

Maybe she has a problem with her weight, and needs your encouragement and support in trying to lose weight. Don't call her fat or say mean things to her, but say encouraging things instead.

You'll have to decide what you're looking for, and that's probably going to call for some modicum of comprehension. Every straight pin has a mass, a volume, a weight, and a density. It also has a length, a diameter, and a DC resistance.
You need to call them for availability
You can call Weight Watchers to ask about this.

Resistance
Technically, a satellite in free-fall (and orbit is a special case of "free-fall") is effectively weightless. What we call weight is the force of the RESISTANCE to gravity; I "weigh" 220 pounds because I an standing on the Earth. The satellite has its own mass, and this can be anything from "tiny" to "enormous".
You can call air resistance anything you like, but it isn't inertia. It's friction.
