Final answer:
The machines that workers use are considered physical capital, which alongside human capital and labor, contributes to the aggregate production function of an economy.
Explanation:
The machines that workers have to work with are considered physical capital. Physical capital refers to machines, production facilities, and other material goods used in the production of other goods and services.
