It is the unit used to measure energy or work. The definition is that one joule is equal to the energy used to accelerate a body with a mass of one kilogram, using one newton of force, over a distance of one meter

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 does one thousand watts equal?
That is called a kilowatt (kW). It is also equal to 1000 joules/second.
What is Planck's constant dimensionally equal to?
Planck's Constant is dimensionally equal to Angular Momentum. The unit is Joules second.
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.
How are watts and joules related?
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!
What unit is power measured in?
The SI unit for power is the watt, which is equal to joules/second.The SI unit for power is the watt, which is equal to joules/second.The SI unit for power is the watt, which is equal to joules/second.The SI unit for power is the watt, which is equal to joules/second.
What is the unit measure for power?
The watt, which is equal to joules/second.

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 does power times time equal?
Power is defined as energy per unit time or Joules per second if you use SI units. This means that multiplying power by time leaves Joules, or energy. Power times time = energy
What is the SL unit of power?
I don't know about SL. If you mean SI, the unit of power is the watt (equal to joules/second).
How many joules is equal to 7.456?
31.22 joules.
What is practical unit of power?
Power is usually measured in watts, which is equal to joules/second. Metric prefixes may be used, such as (for larger amounts of power) kilowatts or megawatts.
How long does it take to do 432 joules of work with 75 watts of power?
A watt is equal to 1 Joule per second. So 432 Joules * (1 / 75 Joules per second) = 432/75 = 5.76 seconds.
What is the rate at witch electrical energy is converted to another type of energy?
That is called "power". The SI unit for power is the watt, which is equal to joules/second.
How many watts are 4680000000joules?
Watts are a measure of power, Joules are a measure of energy. The energy is equal to the power times the time. So if you have a power of 5 watts running for 7 seconds, that is 5x7 Joules of energy, or 35 Joules. Looked at another way, power measures how fast energy is converted. So 35 Joules converted in 7 seconds would be 5 watts of power, but it would need 35 watts to convert that energy in 1 second.
How do you convert from killi joules to joules?
To convert from kilo joules to joules you have divide by 1000 as 1 kilo joule is equal to 1000 joules. E.g. 2 kilo joules equals 2000 joules.
