What Is The Difference Between Joule And Joule Per Second?

The joule-second (symbol 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-second is a unit of action or of angular momentum. ... 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} .

What is the difference between joule and joule?

What is Joules per second equal to?

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.

How do you convert Joules to Joules per second?

1. joule per hour to joules per second = 0.00028 J/s.
2. joules per hour to joules per second = 0.00056 J/s.
3. joules per hour to joules per second = 0.00083 J/s.
4. joules per hour to joules per second = 0.0011 J/s.
5. joules per hour to joules per second = 0.0014 J/s.

How much force is a joule?

1 joule of work = 1 N of force x 1 m of distance

In the English system of units, where force is measured in pounds, work is measured in a unit called the foot-pound (usually abbreviated ft-lb).

How many joules is 1000 watts?

A kilowatt is equal to 1000 watts, so 1 kWh represents the amount of energy transfer that occurs over one hour from a power output of 1000 watts (i.e., joules per second). Thus 1 kWh is equal to 3,600,000 joules of energy transfer (work).

Which of the following is equal to 1 joule?

One joule equals the work done (or energy expended) by a force of one newton (N) acting over a distance of one meter (m). One newton equals a force that produces an acceleration of one meter per second (s) per second on a one kilogram (kg) mass. Therefore, one joule equals one newton•meter.

What do you mean by 1 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. ... In electrical terms, the joule equals one watt-second —i.e., the energy released in one second by a current of one ampere through a resistance of one ohm.

Which is another form of 1 joule?

Answer. Explanation: A watt-second (symbol W s or W. s) is a derived unit of energy equivalent to the joule.

How do you calculate joules?

Multiply watts by seconds to get joules .

If you multiply the number of watts by the number of seconds, you’ll end up with joules. To find out how much energy a 60W light bulb consumes in 120 seconds, simply multiply (60 watts) x (120 seconds) = 7200 Joules.

Is joule a SI unit?

The SI unit for work and energy commonly used in drawing is the joule (J), which is equivalent to a force of one newton exerted through a distance of one meter (m). ... Energy in the UK/US system is often expressed as British thermal units (Btu), with 1 Btu equal to 1.0543 × 10 ³ J.

How do you calculate joules per hour?

1. watt to joules per hour = 3,600.00 J/hr.
2. watts to joules per hour = 7,200.00 J/hr.
3. watts to joules per hour = 10,800.00 J/hr.
4. watts to joules per hour = 14,400.00 J/hr.
5. watts to joules per hour = 18,000.00 J/hr.
6. watts to joules per hour = 21,600.00 J/hr.

Is 1000 joules a lot?

A unit with up to 1000 joules of surge protection is adequate for these small electronics. ... A surge protector with 1000 to 2000 joules will provide sufficient protection for power tools and office equipment such as printers, copiers and routers.

How many joules is a punch?

The kinetic energy of a punch varies greatly. While beginners might only be able to muster a measly 37.5 joules of energy, experts can deliver over 400 joules , an amount roughly equal to getting shot by a handgun!

What is Newton formula?

Force (Newton) = Mass of body × Acceleration . Or, F = [M ¹ L ⁰ T ⁰ ] × [M ⁰ L ¹ T ^{– 2} ] = M ¹ L ¹ T ^{– 2} . Therefore, Newton is dimensionally represented as M ¹ L ¹ T ^{– 2} .

How many volts is 1000 joules?
