## Who is the unit joule named after?

James Prescott Joule

James Prescott Joule, (born December 24, 1818, Salford, Lancashire [now in Greater Manchester], England—died October 11, 1889, Sale, Cheshire), English physicist who established that the various forms of energy—mechanical, electrical, and heat—are basically the same and can be changed one into another.

## Why the SI unit of work and energy is joule?

Explanation: The amount of work done is equal to the energy used and both are measured in JOULES (J). It takes energy to lift a weight a certain distance, because you have to do work against the force of gravity.

**How do you explain joules?**

One joule is defined as the amount of energy exerted when a force of one newton is applied over a displacement of one meter. One joule is the equivalent of one watt of power radiated or dissipated for one second. In some applications, the British thermal unit (Btu) is used to express energy.

**Is joule a derived unit?**

The joule is a derived unit defined as the work done, or energy required, to exert a force of one newton for a distance of one meter, so the same quantity may be referred to as a newton meter or newton-meter (also with metre spelling), with the symbol N·m or N m. It can also be written as kg·m2·s−2.

### Why work and energy have the same units?

They share the same units, because they are equivalent – perhaps separated only as cause and effect. Energy is the ability to do work. So the units or one are the units of the other.

**Why energy is measured in the same unit as work?**

Energy is measured in the same unit as work because energy is defined via work (i.e. the capacity of a physical system to do work), the SI unit for energy is the same as the unit of work Joule (J).

**What is a joule in Chem?**

The joule (J) is the SI unit of energy and is named after English physicist James Prescott Joule (1818–1889). Then, in terms of SI base units a joule is equal to a kilogram times meter squared divided by a second squared (kg×m2s2) ( kg × m 2 s 2 ) .

## Is joule unit of energy?

2 days ago

joule, unit of work or energy in the International System of Units (SI); it is equal to the work done by a force of one newton acting through one metre.

## How many joules are there in one unit of energy?

In relation to the base unit of [energy] => (joules), 1 Joules (J) is equal to 1 joules , while 1 Atomic Unit Of Energy (au) = 4.359744E-18 joules .

**Which electrical unit is equivalent to one joule?**

(wɒt) n. the SI unit of power, equivalent to one joule per second and equal to the power in a circuit in which a current of one ampere flows across a potential difference of one volt.

**What are the SI units that make up a Joule?**

Joule, unit of work or energy in the International System of Units (SI); it is equal to the work done by a force of one newton acting through one metre. Named in honour of the English physicist James Prescott Joule, it equals 107 ergs, or approximately 0.7377 foot-pounds.

### Is a Joule considered a SI unit?

The joule (symbol: J) is the basic SI unit of energy . A joule is equal to the kinetic energy of a kilogram mass moving at the speed of one meter per second (one joule is a kg⋅m 2 ⋅s −2).
