What are Joules a combination of?
The joule is a derived unit equivalent to a newton-meter, or a kilogram-meter squared per second per second.The joule is the unit of energy in the International System of Units, also known as SI. It measures heat, electricity and mechanical work. It was named after English physicist James Prescott Joule.For more information see the answer to the Related Question.
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.

What is the difference between a Newton and a Newton Meter?
A Newton meter is a device that measures force. The simple ones that you typically see in high school laboratories use a spring that stretches or is compressed as a force is applied. They have an indicator needle that shows how much force is applied. See link below for a picture. More sophisticated ones typically use load cells to more accurately measure the force. Some people believe they were invented by Isaac newton but this is not the case. The SI unit of force is called a Newton in his honor. Since these meters measure force they are named after this unit. There is sometimes confusion with a Newton Meter (note different spelling) which is the SI unit of torque. (Turning force.)
What are the basic units of watt?
The Watt is the unit for power in the SI system, defined as 1 Joule per second. A Joule is the work done in moving 1 meter against a force of 1 Newton. If you are not familiar with the metric system, you may like to know that 1 kilowatt (1000 watts) is equal to 1.341 horsepower. In electrical work the Watt is (volts x amps), that is the same quantity as 1 Joule/sec, which makes it easy in the metric system to work with mechanical and electrical quantities at the same time.

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.
Which SI unit for energy is also called the newton-meter?
The newton metre is a unit of torque (or moment).
What are the differences between James watt and sir isaac newton?
james watt studied as an instrument maker and sir isaac newton studied mathematics and astromy
What are terms for energy?
BTU, calorie, erg, foot pound, electron volt, watt hour, newton meter
How many voltmeter and ammeter are in dc watt meter?
There is no volt meter or amp meter in a DC watt meter.
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.
A watt is equal to the amount of work that is accomplished when a force of one newton moves an object a distance of one meter?
Not quite, but you're very close to the right track.When a force of one newton acts through a distance of one meter, as youdescribed it, the amount of work done is one joule .If you did it in one second, then the power of that action was one watt.
What is the MKS unit of pressure?
The MKS (meter-kilogram-second) unit of pressure is the pascal (Pa), which is defined as one newton per square meter.
How do you write the quantity 40W in terms of newtons?
Watt is a unit of power, newton is a unit of force. 1 joule (unit of enrgy) is equal to one newton-meter, and one watt (unit of power) is equal to one joule/second, so 1 W = 1 Nm/s.
Why you reset the zero point on the watt meter?
So that the result that you find on the watt meter after resetting it will be accurate
What is one joule the same as?
1 joule is the same (by definition) as 1 newton x 1 meter. It is also the same as 1 watt x 1 second.
