erg per second
- Definition: Erg per second is a unit of power in the centimeter-gram-second (CGS) system, representing the rate at which work is done or energy is transferred. One erg per second is equivalent to one erg of energy expended in one second.
- Symbol: The symbol for erg per second is “erg/s”.
- Usage: Erg per second is primarily used in fields that utilize the CGS system, such as certain branches of physics and engineering. It is less common in daily use compared to the more widely adopted joule per second.
joule per second
- Definition: Joule per second, also known as a watt, is a unit of power in the International System of Units (SI). It denotes the amount of energy transferred or converted per unit time, where one joule per second represents one joule of energy used in one second.
- Symbol: The symbol for joule per second is “W”, which stands for watt.
- Usage: Joule per second is the standard unit of power in most scientific and engineering applications. It is commonly used in electrical systems, mechanical systems, and various energy-related calculations.
Origin of the erg per second
- The erg originated from the CGS system, which was developed in the 19th century. It was defined based on the force needed to move an object and has its roots in classical mechanics. The term “erg” itself is derived from the Greek word “ergon,” meaning work. The erg per second unit reflects the historical context of measuring energy and power in a system that emphasizes smaller scale measurements, particularly in physics.
Origin of the joule per second
- The joule was named after the English physicist James Prescott Joule, who made significant contributions to the understanding of energy and thermodynamics in the 19th century. The joule as a unit of energy was established as part of the SI system to standardize measurements across different scientific disciplines. The joule per second, or watt, became widely accepted as a standard unit of power, facilitating communication and research in various fields.
