This is a very good question. A joule is a unit of energy, and a watt is a unit of power. Power is the rate at which energy is converted from potenital to kinetic energy. So power is some quantity of energy divided by some unit of time. In the SI system, a watt is equal to 1 joule per second. Real life example. A 60W lightbulb uses 60 joules of energy every second. Hope this helps!

How much power is needed to do 1200 Joules of work in 90 seconds?
Power is measured in watts, or joules per second. So in 90 seconds, 1200 joules of work is equal to 1200/90 watts or 13.3 watts.
How you convert 36watts in joules?
Watts is a unit of power; Joules is a unit of energy. Watts means Joules/second, so you would need to know how long a machine that uses 36 watts (for example, certain light-bulbs) is used.36 watts is simply 36 Joules per second; this is the same as 2160 Joules per minute, or 129,600 Joules per hour.Since the electricity bill is measured in kWh instead of Joule (1 kWh = 3,600,000 Ws = 3,600,000 Joule), you might also say that a device that uses 36 watts uses 0.036 kWh every hour.
What is the rate at which work is done?
Work is energy, measured in joules. The rate of work, or joules per second, is known as watts, or power.
What is the energy weight of 100 joules per second?
100 Joules / sec = 100 Watts Example of 100 Watts: (Taking g as 10 (m/s)/s) Lift 10 kg 1 metre in 1 second Power = energy change / time = mgh / 1 = 100 / 1 = 100 Watts
What does one thousand watts equal?
That is called a kilowatt (kW). It is also equal to 1000 joules/second.
How many joules of light energy are in 1440 watts of electrical energy?
A joule is a joule, whether it be electrical energy or light energy - although commonly, lamps are not 100% efficient.On the other hand, you can't convert joules directly to watts. Watts means joules per second (joules / second), or equivalently, joules is watts times seconds.A joule is a joule, whether it be electrical energy or light energy - although commonly, lamps are not 100% efficient.On the other hand, you can't convert joules directly to watts.

What is the relationship between watts and energy output?
Watts is energy output. Watts is joules per second. Joules is energy.
How many joules are in 59.4 watts?
"59.4 watts" means "59.4 joules every second"
Calculate the power in watts used if you exert 50 joules of work in 5 seconds?
Watts is joules per second, so 50 joules in 5 seconds is 10 watts.
What is joules divided by seconds?
watts
What is the conversion from joules of energy to watts of energy?
There is no conversion, as joules measures energy and watts measures power -two different quantities!
How much power is needed to do 1200 Joules of work in 90 seconds?
Power is measured in watts, or joules per second. So in 90 seconds, 1200 joules of work is equal to 1200/90 watts or 13.3 watts.
What is the energy used in one second when a bulb have 40Watts.?
40 Joules, I think, as the formula for Watts is Joules/Second = Joules per second 40 Watts should equal 40 Joules per one second...
How much energy is needed to get a small electromagnet up to 1.6 Tesla it can be in joules watts or volts?
It had better be in joules. Watts and volts are not units of energy. yes, but how many as in ? joules/sec
How much power is involved if 1800 joules of work are done in 1 minute?
1800 joules / 1 minute = 1,800 joules / 60 seconds = 30 joules per second = 30 watts.
How many watts are 6.48million joules?
75
Are watts measured by Joules divided by meters or Joules divided by seconds?
joule/sec
