In other words, to understand what Joules * seconds means, one must understand the terms by themselves. In SI base units the joule-second becomes kilogram-meter squared-per second or kg⋅m2⋅s−1. Schlamminger, S.; Haddad, D.; Seifert, F.; Chao, L. S.; Newell, D. B.; Liu, R.; Steiner, R. L.; Pratt, J. R. (2014). Voor het uitdrukken van een hoeveelheid elektrische energie wordt deze eenheid dan ook vaak gebruikt.

Another example is the use of kilowatt-hour as a unit of energy. Storing 10,000 joules for 400 seconds would cost a certain amount. It is the unit of Planck’s constant, one of the fundamental physical constants. "Determination of the Planck constant using a watt balance with a superconducting magnet system at the National Institute of Standards and Technology." Joule per second (J/s), power. Watt/Square Meter : The watt per square meter is a derived unit of heat flux density in the International System of Units SI. Note the denominator of seconds (s) in the base units. Convert power of joule per second (J/s) and watts (W) units in reverse from watts into joules per second. The joule-second should not be confused with the physical process of joules per second (J/s).. Joules per second: In physical processes, when the unit of time appears in the denominator of a ratio, the described process occurs at a rate. Power units.

The joule-second should not be confused with the physical process of joules per second (J/s). Confusion with joules per second. 1 Joules per second = 0.0013 Horsepower: 10 Joules per second = 0.0134 Horsepower: 2500 Joules per second = 3.3526 Horsepower: 2 Joules per second = 0.0027 Horsepower: 20 Joules per second = 0.0268 Horsepower: 5000 Joules per second = 6.7051 Horsepower: 3 Joules per second = 0.004 Horsepower: 30 Joules per second = 0.0402 Horsepower: 10000 Joules per second = 13.4102 Horsepower Then click the Convert Me button. This product of moment of inertia and angular velocity yields kg⋅m2⋅s−1 or the joule-second.

Its symbol is W/m². So, what 500 J.s means, is that there is a source of energy that I can use in the following manner: 500 Jules for 1 second; or 250 Jules for 2 seconds; or 100 Jules for 5 seconds; or 1 Jule for 500 seconds; or in any combination of numbers who's product is 500![4]. The joule-second (J⋅s or J s) is the product of an SI derived unit, the joule (J), and an SI base unit, the second (s). The Joule is a unit of energy and the second is a unit of time.

As an example for the above formula; a .20 gram bb is moving at 328 feet per second [.5 * (.20 grams / 1000 kilograms) x (328 feet per second x .3048 meters per second) ^2 is equal to 0.999488 or 1 Joule. Planck's constant represents the energy of a wave, in units of joule, divided by the frequency of that wave, in units of s−1.

Type the number of Joule per second (J/s) you want to convert in the text box, to see the results in the table. joules-second: To understand joules x second (J⋅s) we can imagine the operator of an energy storage facility quoting a price for storing energy. KE = 0.5 . The joule-second also appears in quantum mechanics within the definition of Planck's constant. In physics, work per time describes a system’s power; defined by the unit watt (W), which is joule per second (J/s). Note that rounding errors may occur, so always check the results. De vermenigvuldiging van de watt (joule per seconde) met een tijdseenheid heeft weer een eenheid van energie als gevolg. https://en.wikipedia.org/w/index.php?title=Joule-second&oldid=985253799, Creative Commons Attribution-ShareAlike License, This page was last edited on 24 October 2020, at 21:49. Storing double the energy for half the time would use the same resources, and cost the same. To switch the unit simply find the one you want on the page and click it. KE ( in Joules) = 0.5 ( a half) x the mass of the something (in kg) x the speed squared (in Meters/Second) or. This is a conversion chart for joule per second (Common Units). Ben Ch presented the answer that energy per unit time is power. 1 watt is equal to 3600 joule/hour, or 1 joule per second. 3 m . v^2. Dimensional Analysis of the joule-second yields M L2 T−1. One watt per square meter is equal to 1J/s•m². Een apparaat van 10 watt verbruikt in 24 uur: ∗ = =, Metrologia. Joule/Second Square Meter : The joule per second per square meter is a … [1] The joule-second is a unit of action or of angular momentum. 2: Enter the value you want to convert (joule per second). Joules per second: In physical processes, when the unit of time appears in the denominator of a ratio, the described process occurs at a rate. That is called the action integral. In this case, we are using the rate of energy output multiply by the time over which the output exists, to represent the total energy[3]. Your value gets instantly converted to all other units on the page. The other question is what is the product of energy by time. [2] Angular momentum is the product of an object’s moment of inertia, in units of kg⋅m2 and its angular velocity in units of rad⋅s−1. For example, in discussions about speed, an object like a car travels a known distance of kilometers spread over a known number of seconds, and the car’s rate of speed becomes kilometers per second (km/s). You can also go to the universal conversion page. Type in your own numbers in the form to convert the units!
