I suggest trying this formula;Here I am using the work as understood by "physics". A plant growing using solar energy represents work by the plant, an animal pulling a cart is also work, so is regular labor and machines using any source of energy to operate.
(HE x T) + R = W
HE = Human Energy. We could consider this what you want to call "work". But it also includes vision, planning, organizing as well as Labor in various forms.
T = Tools. This can include a large range of items and concepts. Knowledge and Skills to start with, and the schools and institutions for learning such. Basic implements such as saws and hammers, picks and shovels, etc. Then "power" from animal strength/labor to water/wind mills, to coal plants, smelters, dams with hydro-electric generators, etc. Transportation systems such animal drawn plows and wagons to motor vehicles to steamships to airplanes, trucks, trains, etc. Along with smelters, refineries, there are factories, markets and even financial systems such as banks and stock exchanges (investment systems for 'capital').
R = Resources. Mostly natural mineral and metal-ores. Also includes the soil for agriculture and the Foods it produces, and seas and oceans for marine fisheries. Trees for lumber and other wood products, oil wells for petroleum, mines for mineral and metal ores. Basically the materials needed to be crafted into "Goods", physical items.
W = Wealth. Goods and/or Services with Market Value. The end result of Production Efforts.
(Human Energy times(x) Tools) plus(+) Resources equals(=) Wealth
(HE x T) + R = W
