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

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?
- joule per hour to joules per second = 0.00028 J/s.
- joules per hour to joules per second = 0.00056 J/s.
- joules per hour to joules per second = 0.00083 J/s.
- joules per hour to joules per second = 0.0011 J/s.
- 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?
- watt to joules per hour = 3,600.00 J/hr.
- watts to joules per hour = 7,200.00 J/hr.
- watts to joules per hour = 10,800.00 J/hr.
- watts to joules per hour = 14,400.00 J/hr.
- watts to joules per hour = 18,000.00 J/hr.
- 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!
