Scientific definitions for joule (1 of 2)

**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 10^{7} ergs, or approximately 0.7377 foot-pounds.

Secondly, what is a joule equal to in terms of kg M and S? As any physics student can tell you, a **Joule** is one **kilogram** – meter squared per second squared. A force of 1 Newton changes the speed of a mass of 1 **kilogram** in one meter per second each second.

Subsequently, one may also ask, what base units make up a joule?

The joule (symbol J) is the SI unit of energy—a measure of the capacity to do work or generate heat. One joule equals the work done (or energy expended) by a force of one **newton** (N) acting over a distance of one meter (m).

### What is the unit for work?

Units. The SI unit of work is the joule (J), which is defined as the work expended by a force of one newton through a displacement of one metre.

### Which is the largest unit of energy?

Joule

### What is Joule’s made up of?

Joule. It is equal to the energy transferred to (or work done on) an object when a force of one newton acts on that object in the direction of the force’s motion through a distance of one metre (1 newton metre or N⋅m).

### What do you mean by 1 Joule?

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 a joule a Newton meter?

A joule (J) is a derived unit of energy, work, and amount of heat in the International System of Units SI. The joule is equal to the energy expended or work done in applying a force of one newton through a distance of one meter (1 newton meter or N·m).

### How do you convert joules to Watts?

Power is equal to the energy in joules divided by the time in seconds. For example, find watts of power for 250 joules of energy over 40 seconds. You might also like our watts to amps converter for converting power to current.

### How do you convert joules to MS?

The answer is 9.80665. We assume you are converting between joule/second and kilogram-force meter/second. You can view more details on each measurement unit: joules/second or kg-m/s The SI derived unit for power is the watt. 1 watt is equal to 1 joules/second, or 0.10197162129779 kg-m/s.

### What are the units of Pascals?

The pascal (symbol: Pa) is the SI derived unit of pressure used to quantify internal pressure, stress, Young’s modulus and ultimate tensile strength. The unit, named after Blaise Pascal, is defined as one newton per square metre. The unit of measurement called standard atmosphere (atm) is defined as 101325 Pa.

### What is Joule per kg?

Joule Per Kilogram (J/kg) is a unit in the category of Thermal heat capacity. It is also known as joule/kilogram, joules per kilogram. This unit is commonly used in the SI unit system. Joule Per Kilogram (J/kg) has a dimension of L2T-2 where L is length, and T is time.

### What units are a Newton?

Definition. A newton (N) is the international unit of measure for force. One newton is equal to 1 kilogram meter per second squared. In plain English, 1 newton of force is the force required to accelerate an object with a mass of 1 kilogram 1 meter per second per second.

### What is the unit for momentum?

The unit of momentum is the product of the units of mass and velocity. In SI units, if the mass is in kilograms and the velocity is in meters per second then the momentum is in kilogram meters per second (kg⋅m/s).
