Definition of Erg - Physics & Math Explained

In summary, an erg is a unit of energy, work, or heat in the centimeter-gram-second system of units. It is typically measured using an ergometer or calculated using the formula W = F * d. One erg is equivalent to a very small amount of energy compared to other common units. Ergs are commonly used in scientific experiments and calculations, as well as in fields such as biomechanics and exercise physiology. There is a difference between erg and ergonomics, with erg being a unit of measurement and ergonomics being the study of designing tools and environments for the human body.

i would appreciate a simple definiton of "erg" relating to physics. i hope this is in the right forum. i was told ergodic is the math behind erg. i don't speak any japanese, but i do know a little german. thank you.

An erg is the cgs unit of energy equal to 1 dyne*cm. It is related to the SI unit (Joules) by 1 J=107 erg.

FAQ: Definition of Erg - Physics & Math Explained

What is the definition of erg in physics and math?

An erg is a unit of energy, work, or heat in the centimeter-gram-second system of units. It is equal to the amount of work done by a force of one dyne over a distance of one centimeter.

How is erg measured?

Ergs are typically measured using a tool called an ergometer, which measures the amount of work done by a person or machine. Alternatively, they can also be calculated using the formula W = F * d, where W is work in ergs, F is the force in dynes, and d is the distance in centimeters.

What is the conversion rate for ergs to other units of energy?

One erg is equivalent to 10^-7 joules, 2.39006 * 10^-8 calories, or 0.6241514 * 10^-11 watt-hours. In other words, 1 erg is a very small amount of energy compared to other common units.

How are ergs used in physics and math?

Ergs are often used to measure small amounts of energy or work in scientific experiments and calculations. They are also commonly used in fields such as biomechanics and exercise physiology to measure the energy expended during physical activity.

Is there a difference between erg and ergonomics?

Yes, there is a difference between erg and ergonomics. Erg refers to a unit of energy or work, while ergonomics is the scientific study of designing tools, equipment, and work environments to fit the capabilities and limitations of the human body.
