The rate of doing work is called:

Power is defined as the rate of doing work. In the International System of Units, the unit of power is the watt, equal to one joule per second.

Power is the measure of how quickly work is done or energy is transferred. In simpler terms, it indicates the rate at which a force moves an object or performs work over time. The concept of power is closely related to both work and time; it quantifies the amount of work completed in a specific time frame.

In the International System of Units (SI), the standard unit for measuring power is the watt (W). One watt is defined as the rate of doing work when one joule of energy is used per second. This means that if an object is lifted or moved by a force and one joule of energy is required to do so in one second, the power involved in that process is one watt.
