Answer 1

Ответ:

За единицу работы принимают работу,совершаемую силой 1Н на пути,равном 1м.

Единица работы-джоуль (Дж) названа в честь английского учёного Джоуля.Таким образом

Definition of the Joule (J) as a Unit of Work

The Joule (J) is the standard unit of work in the International System of Units (SI). It is defined as the amount of work done when a force of one newton is applied over a distance of one meter in the direction of the force. In other words, one Joule is equal to the work done when a force of one newton moves an object one meter in the direction of the force.

Other Units of Work

In addition to the Joule, there are other units of work that are used in different contexts. Some of these units include:

1. Erg (erg): The erg is a unit of work in the centimeter-gram-second (CGS) system. One erg is equal to the work done by a force of one dyne (the CGS unit of force) acting over a distance of one centimeter.

2. Foot-Pound (ft-lb): The foot-pound is a unit of work commonly used in the United States. It is defined as the work done when a force of one pound is applied over a distance of one foot.

3. Calorie (cal): The calorie is a unit of work often used in the field of nutrition and energy. It is defined as the amount of work required to raise the temperature of one gram of water by one degree Celsius.

4. Kilowatt-Hour (kWh): The kilowatt-hour is a unit of work commonly used to measure electrical energy consumption. It is defined as the work done by a power of one kilowatt over a period of one hour.

These are just a few examples of units of work that are used in different fields and contexts. The choice of unit depends on the specific application and the system of units being used.
