What is the unit of measurement used to express the energy emitted per second?
Power. In SI, energy is measured in Joule, and power is measured to watts (= Joule per second).Power. In SI, energy is measured in Joule, and power is measured to watts (= Joule per second).Power. In SI, energy is measured in Joule, and power is measured to watts (= Joule per second).Power. In SI, energy is measured in Joule, and power is measured to watts (= Joule per second).
The basic unit of lenght in the metric system is?
The unit of work is the joule. One joule is the work done, or the energy used, moving a force of one newton a distance of one metre.
What is power and what is the unit for power?
Power is the rate of use of energy in time. The unit of Energy is joule and the unit of Power is joule/second or Watt.
How many watts equals 1 joule?
Watts are units of power. Joules are units of energy. They are not the same. One watt is one joule per second.
Is watt a unit of energy?
Joule is a unit of energyWatt is a unit of power
How does watt and joule relate?
The Joule is a unit of energy, while the Watt is a unit of power. Joule is the alternate name for a Newton-meter of energy, and Watt is the alternate name for a Newton-meter per second of power. This means that one Watt is one Joule per second; a 100-Watt light bulb converts 100 Joules of electrical energy every second into heat energy and light energy.

A unit of energy is the unit of what?
... is called power. The SI unit for energy is the joule; the SI unit for power is joule/second = watt.
How much is one Watt of energy?
A watt is a unit of power, not of energy. The international unit for energy is the joule. One watt is an energy transfer of one joule per second.A watt is a unit of power, not of energy. The international unit for energy is the joule. One watt is an energy transfer of one joule per second.A watt is a unit of power, not of energy. The international unit for energy is the joule. One watt is an energy transfer of one joule per second.A watt is a unit of power, not of energy. The international unit for energy is the joule. One watt is an energy transfer of one joule per second.
What are the differences between a joule and a watt?
Joules versus wattsThe joule and the watt are closely related units. The joule is a unit of work and energy. It is equal to a newton-meter (N-m). Note that the unit of torque is also the newton-meter, but scientists don't use the word joule when they are talking about torque.The watt is a unit of power and is defined as a joule per second, so you can see that power is work per unit time.One joule is equal to one watt-second.
The basic unit of lenght in the metric system is?
The unit of work is the joule. One joule is the work done, or the energy used, moving a force of one newton a distance of one metre.
Is a watt and a newton equivalent units?
The watt is the SI derived unit for power, it is defined as joules per second, and measures the rate of energy transfer or conversion. The unit for work is the joule. The joule is the derived unit for energy, work, and heat ( heat energy, not temperature). One joule is the energy used, or work done, applying a force of one newton for a distance of one metre; or passing one ampere across a resistance of one ohm for one second.
Is a watt a unit of power or a unit of electrical energy?
Watt is a unit of power. 1 Watt = 1 Joule/second; joule is the unit for energy.
What is power and what is the unit for power?
Power is the rate of use of energy in time. The unit of Energy is joule and the unit of Power is joule/second or Watt.
In what unit is electromagnetic energy measured in?
All energy is measured in joules. A joule is a Newton meter.One joule is defined as the amount of work done by a force of one newton moving an object through a distance of one meter. It is also the work required to continuously produce one watt of power for one second; or one watt second (W·s)
What is the difference in newton and joule?
Newton is a measure of force, Joule is a measure of work done. Newton refers to the mechanical energy of moving matter, while joule refers to any form of energy possessed by matter. E.g. W = f X d where W is work in joules, f is force in newtons, and d is distance in meters.
