Final answer:
Power is defined as the rate at which work is done, represented mathematically as P = W/t, where P is power, W is work, and t is time.
Step-by-step explanation:
Power is the rate of work done on an object or system. To understand power in the context of physics, consider the equation for power: P = W/t, where P stands for power, W represents the work done, and t is the time over which the work is performed. This concept can be visualized when looking at mechanical or electrical systems that transfer energy at varying rates;
power quantifies how quickly this energy transfer occurs. It is fundamentally different from force, energy, or resistance, which may be involved in calculating work done but do not define the rate at which energy is transferred.
