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


How many watts per hour to equal 1000 btu's?

The energy unit is not watts per hour, but watts times hour, simply called watt-hours.One BTU is equal to about 1055 Joules or Watt-seconds; that is about 0.293 watt-hours. Actually there are different definitions of the BTU.The energy unit is not watts per hour, but watts times hour, simply called watt-hours.One BTU is equal to about 1055 Joules or Watt-seconds; that is about 0.293 watt-hours.

How many joules are in 59.4 watts?

"59.4 watts" means "59.4 joules every second"


How many joules of light energy are in 1440 watts of electrical energy?

To calculate the energy in joules, you can use the formula: energy (joules) = power (watts) × time (seconds). If you have 1440 watts of electrical power and want to calculate the energy in joules for a specific time period, you would need to know the time duration in seconds.


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 the conversion from joules of energy to watts of energy?

Power (watts) is a measure of energy transfer over time, while energy (joules) is a measure of total work done. The formula to convert energy in joules to power in watts is: Power (watts) = Energy (joules) / time (seconds).


How many watts in 7000 joules?

To convert joules to watts, you need to know the time over which the energy is expended. Since power in watts is defined as energy in joules divided by time in seconds, you cannot directly convert 7000 joules to watts without knowing the time duration.


How many joules are in 100 watts?

There are 100 joules in 1 watt-second, so in 1 second, there would be 100 joules per watt. Therefore, in 100 watts, there would be 10,000 joules.


What is joules divided by seconds?

How long does it take to perform 475 Joules of work with 25 watts of power?

To calculate the time it takes to perform 475 Joules of work with 25 watts of power, you use the formula: time = work / power. In this case, time = 475 Joules / 25 watts = 19 seconds. So, it will take 19 seconds to perform 475 Joules of work with 25 watts of power.


How much power is a 150 joules?

Oh, dude, 150 joules is like the amount of energy needed to lift a medium-sized apple about a meter off the ground. So, it's not a ton of power, but hey, it's something. Just enough to make you go, "Hmm, interesting," and then move on with your day.
