Answer: Money
Explanation:
Both money and energy are part of a cycle.
What does this mean?
Energy is not created nor destroyed, it is transformed into other forms of energy (for example: thermal energy, acoustic energy, kinetic energy, among others). Something similar happens with the flow of money in economic transactions, in which money is exchanged for products, work or services and continues its flow in the market.
Therefore, energy is a physical quantity with properties somewhat similar to money.
