The electronvolt (eV) is a unit of energy commonly used in the fields of physics and chemistry. It is defined as the amount of kinetic energy gained or lost by a single electron when it is accelerated through an electric potential difference of one volt. This unit is particularly useful for measuring small amounts of energy, such as those encountered in atomic and subatomic processes.
The electronvolt is part of the International System of Units (SI) but is not an SI unit itself. Instead, it is derived from the SI unit of energy, the joule (J). Specifically, 1 eV is equivalent to approximately (1.602 \times 10^{-19}) joules. This relationship allows for easy conversion between electronvolts and joules, making it a versatile unit in scientific calculations.
The concept of the electronvolt emerged in the early 20th century as physicists began to explore the behavior of electrons and other subatomic particles. The term was first used in 1900, and since then, it has become a standard unit in various scientific disciplines, including particle physics, quantum mechanics, and solid-state physics. Its widespread adoption reflects the growing importance of understanding energy at the atomic level.
To illustrate the use of the electronvolt, consider a scenario where an electron is accelerated through a potential difference of 5 volts. The energy gained by the electron can be calculated as follows:
[ \text{Energy (eV)} = \text{Charge (C)} \times \text{Voltage (V)} = (1.602 \times 10^{-19} \text{ C}) \times (5 \text{ V}) = 8.01 \times 10^{-19} \text{ J} \approx 5 \text{ eV} ]

The Newton Meter (N·m) is a vital unit of measurement in the field of physics and engineering, representing torque or rotational force. This tool allows users to convert and understand the relationship between force and distance, making it essential for various applications, from mechanical engineering to physics experiments.
A Newton Meter is defined as the torque resulting from a force of one Newton applied perpendicularly to a lever arm that is one meter long. It is a crucial unit when dealing with rotational dynamics, ensuring that calculations involving torque are accurate and meaningful.
The Newton Meter is part of the International System of Units (SI), which standardizes measurements across scientific disciplines. This standardization ensures consistency and reliability in calculations, making it easier for professionals and students alike to communicate their findings effectively.
The concept of torque has been studied since ancient times, but the formal definition of the Newton Meter was established with the development of the SI system in the 20th century. Over the years, the understanding of torque and its applications has evolved, leading to advancements in engineering and technology.
To illustrate the use of the Newton Meter, consider a scenario where a force of 10 N is applied at the end of a 2-meter-long lever arm. The torque can be calculated as follows:
[ \text{Torque (N·m)} = \text{Force (N)} \times \text{Distance (m)} ] [ \text{Torque} = 10 , \text{N} \times 2 , \text{m} = 20 , \text{N·m} ]
