Joule Dimension

Work (Joule)= F × D = [M1 L1 T-2] × [L1] = [M1 L2 T-2]. Therefore, Joule is dimensionally represented as [M1 L2 T-2].

What is joule unit?

In the SI system, the unit of work or energy is the Joule (J). One Joule represents the work done by a force of 1 Newton moving 1 m in its own direction.

What is the dimension of Joule second?

In SI base units the joule-second becomes kilogram-meter squared-per second or kg⋅m2⋅s−1. Dimensional Analysis of the joule-second yields M L2 T−1. Note the denominator of seconds (s) in the base units.

What is the dimension of joule per kg?

Joule Per Kilogram (J/kg) has a dimension of L2T-2 where L is length, and T is time. This unit is the standard SI unit in this category.

What is dimension formula?

The dimensional formula is defined as the expression of the physical quantity in terms of its basic unit with proper dimensions. For example, dimensional force is. F = [M L T-2] It's because the unit of Force is Netwon or kg*m/s2.

What is the value of 1 joule in ERG?

Therefore, the relationship between joule and erg 1 J = 10 7 erg .

Why joule is 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.

What is joule m2?

It is defined as the total amount of energy per a given area that would be released if all combustible materials in this area burned. SI units for both are joules per square meter or J/m².

Why is joule kg/m2 s2?

A Joule is defined as the energy needed for the work (or the work itself) of moving 1 Newton over 1 meter. So . While a Newton is defined as the force necessary to accelerate 1 kilogram at an acceleration rate of 1 meter per square second: . So, combine both definitions and you have .

Is joule a unit of heat?

Generally, all forms of energy are measured in terms of joules in the SI system. Notably, heat is a form of energy, and therefore the SI unit of heat is also joules (J) which are defined as the amount of energy needed to raise the temperature of a given mass by one degree.

What unit is joule per gram?

A joule per gram per degree Celsius (J/g·°C) is a metric unit of specific heat capacity. A material has a heat capacity of 1 J/g·°С if heat energy of one joule is required to raise the temperature of one gram of this material by one degree Celsius.

What is 1 joule of work in kg?

1 J Is equal to 1 kg m s^-2 | Physics Questions.

Is joule in g or kg?

A joule per gram (J/g) is a decimal unit of absorbed radiation dose. A joule per kilogram (J/kg) is the SI-derived unit of absorbed radiation dose.

What are the 7 basic dimensions?

In total, there are seven primary dimensions. Primary (sometimes called basic) dimensions are defined as independent or fundamental dimensions, from which other dimensions can be obtained. The primary dimensions are: mass, length, time, temperature, electric current, amount of light, and amount of matter.

What are all dimensions?

The world as we know it has three dimensions of space—length, width and depth—and one dimension of time.

What is dimension of value?

Dimension values are tags, or labels, you use to classify the records in your data set. Tagging a record with a dimension value does the following: It organizes the record within the tree structure of the associated dimension.

Is erg in SI unit?

The erg is not an SI unit. Its name is derived from ergon (ἔργον), a Greek word meaning 'work' or 'task'. An erg is the amount of work done by a force of one dyne exerted for a distance of one centimetre. In the CGS base units, it is equal to one gram centimetre-squared per second-squared (g⋅cm2/s2).

What is CGS unit of newton?

The CGS unit of force is . then, 1 newton = 1 kg × 1 m / s 2 = 1000 g × 100 cm / s 2 = 10 5 g × cm / s 2 = 10 5 dyne. Therefore, the relation between SI and CGS unit of force is 1 newton = 10 5 dyne .

How many joules is one watt?

Watts are defined as 1 Watt = 1 Joule per second (1W = 1 J/s) which means that 1 kW = 1000 J/s. A Watt is the amount of energy (in Joules) that an electrical device (such as a light) is burning per second that it's running. So a 60W bulb is burning 60 Joules of energy every second you have it turned on.

Who invented the joule unit?

James Prescott Joule (1818–89) is now rightly revered as one of the greatest scientists in the history of physics, due to his groundbreaking work in thermodynamics.
