The Newton Meter per Second (N·m/s) is a unit of power in the International System of Units (SI). It quantifies the rate at which work is done or energy is transferred. Specifically, one Newton Meter per Second is equivalent to one watt (W), making it a vital measurement in various fields such as physics, engineering, and mechanics.
The Newton Meter per Second is standardized under the SI units, where:
The concept of power has evolved significantly since the early days of physics. The term "watt" was named after James Watt, who made significant contributions to the development of the steam engine in the 18th century. The Newton Meter per Second emerged as a practical unit to express power in mechanical systems, facilitating advancements in engineering and technology.
To illustrate how to use the Newton Meter per Second in calculations, consider a scenario where a force of 10 Newtons is applied over a distance of 5 meters in 2 seconds. The power can be calculated as follows:
[ \text{Power (P)} = \frac{\text{Work (W)}}{\text{Time (t)}} ]
Where Work (W) = Force (F) × Distance (d):
[ W = 10 , \text{N} \times 5 , \text{m} = 50 , \text{J} ]
Then, substituting into the power formula:
[ P = \frac{50 , \text{J}}{2 , \text{s}} = 25 , \text{W} ]
Thus, the power output is 25 N·m/s.

The volt-ampere (VA) is a unit of measurement used to express apparent power in an electrical circuit. It represents the product of voltage (in volts) and current (in amperes) in an AC (alternating current) system. Unlike watts, which measure real power, volt-amperes account for both active and reactive power, making them essential for understanding the performance of electrical systems.
The volt-ampere is standardized under the International System of Units (SI) and is widely recognized in electrical engineering. The symbol for volt-ampere is VA, and it is often used in conjunction with other units to describe the power capacity of electrical devices, such as transformers and generators.
The concept of apparent power, represented by the volt-ampere, emerged as electrical systems evolved in the late 19th century. As AC systems became prevalent, the need for a unit that could encompass both voltage and current became essential. The volt-ampere was introduced to provide a clear understanding of power in AC circuits, distinguishing it from direct current (DC) systems.
To calculate the apparent power in volt-amperes, simply multiply the voltage (V) by the current (I): [ \text{VA} = V \times I ] For example, if a circuit operates at 120 volts and draws 5 amperes, the apparent power would be: [ \text{VA} = 120 , V \times 5 , A = 600 , VA ]
