What is a definition of a joule?
A joule is the unit of measurement for energy or work in the International System of Units (SI). One joule is equal to the work done when a force of one newton is applied over a distance of one meter in the direction of the force.
Converting a Joule to an Erg?
There are 10 million ergs in 1 joule.The erg is the unit of work done - or energy expended - in the centimeter-gram-second (CGS) system of measurement.An erg is equal to .0000001 joule. A joule is the unit of work done - or energy expended - in the meter-kilogram-second (MKS) system.Further information about the jouleA joule is a unit of electrical energy equal to the work done when a current of one ampere is passed through a resistance of one ohm for one second.ANDA joule is a unit of energy equal to the work done when a force of one newton acts through a distance of one 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.
What is the SI counterpart for the English pound?
The SI counterpart for the English pound is the kilogram. One pound is approximately equal to 0.453592 kilograms.
How many joules are equivalent to 1 kilogram meter squared per second squared (kg m2/s2)?
One joule is equivalent to 1 kilogram meter squared per second squared (kg m2/s2).
What is a joule and what does it measure?
he 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. See the related links for more information.The joule is a derived unit equivalent to a newton-meter, or a kilogram-meter squared per second per second.A joule is also:A unit of electrical energy equal to the work done when a current of one ampere is passed through a resistance of one ohm for a period of time of one second.A unit of energy equal to the work done when a force of one newton* acts through a distance of one meter.[* In the meter-kilogram-second (MKS) system, a newton is the unit of force required to accelerate a mass of one kilogram one meter per second per second, equal to 100,000 dynes. The unit is named after Sir Isaac Newton.]
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.

How many kilowatt are in 1 joule?
One joule is equal to 0.00027778 kilowatts when considering the conversion over one second. This is derived from the definition of power, where 1 watt is equal to 1 joule per second. Therefore, to convert joules to kilowatts, you divide by 3,600 (the number of seconds in an hour) to get the kilowatt equivalent.
What unit of electrical power is equal to one joule per second?
One joule per second equates to:One watt or,0.00134 electric horsepower or,3.412 BTUs per hour.
What is the SI counterpart for the English pound?
The SI counterpart for the English pound is the kilogram. One pound is approximately equal to 0.453592 kilograms.
What is another way to write a newton?
A newton can be expressed in terms of base SI units as kg·m/s², which represents the force required to accelerate a mass of one kilogram at a rate of one meter per second squared. Additionally, it can be represented as a derived unit involving the joule and the meter, since one joule is equal to one newton-meter.
How many joules are equivalent to 1 kilogram meter squared per second squared (kg m2/s2)?
One joule is equivalent to 1 kilogram meter squared per second squared (kg m2/s2).
What measures the kinetic energy?
Joules are the SI unit for energy. One Joule is equal to one kilogram meters squared per seconds squared (kgm2/s2).
Why are you using kilogram instead of newton?
A kilogram is a unit of measurement for WEIGHT. A newton (in the meter-kilogram-second system) is the unit of FORCE required to accelerate a mass of one kilogram one meter per second per second, equal to 100,000 dynes.
