Capital
Capital refers to the man-made factors of production that are used in the production process. These can be either purchased or constructed. Some examples of capital are raw material, machinery and factories. Raw materials and component that will become a part of the end product are known as working capital.
Factories and machinery that do not become a part of the end product but are necessary for the manufacturing process are known as fixed capital.
Yet another example of capital is any special training or education paid for by a company to give their workers new and more valuable abilities. This is known as human capital.
