One joule equals the work done (or energy expended) by a force of one newton (N) acting over a distance of one meter (m). One newton equals a force that produces an acceleration of one meter per second (s) per second on a one kilogram (kg) mass.One joule equals the work done (or energy expended) by a force of one newton (N) acting over a distance of one meter (m).

What unit is equivalent to a joule?
watt-second A watt-second (symbol W s or W·s) is a derived unit of energy equivalent to the joule. The watt-second is the energy equivalent to the power of one watt sustained for one second.
Is 1 joule the same as 1 watt?
Watts (W) and Kilowatts (kW): Watts are defined as 1 Watt = 1 Joule per second (1W = 1 J/s) which means that 1 kW = 1000 J/s. A Watt is the amount of energy (in Joules) that an electrical device (such as a light) is burning per second that it's running.
What is the equivalent of 1 joule per second?
one watt Yes. one joule per second is equivalent to one watt. The SI units for work and time are Joules and seconds, respectively. Therefore, One Watt was defined as a power of 1 Joule per second.
What is a joule equal to in KG?
Joule to Kilogram-force Meter Conversion Table
| Joule [J] | Kilogram-force Meter |
|---|---|
| 0.1 J | 0.0101971621 kilogram-force meter |
| 1 J | 0.1019716213 kilogram-force meter |
| 2 J | 0.2039432426 kilogram-force meter |
| 3 J | 0.3059148639 kilogram-force meter |
What is meant by 1 joule of work?
1 J is the amount of work done by a force of 1 N on an object that displaces it through a distance of 1 m in the direction of the applied force. 1 J = 1 N x 1 m.
What is the formula of 1 joule?
1 Joule = 1 Newton × 1 Mete 1 Joule is defined as the work done or energy transferred to an object when a one Newton force acts on it over one meter. Joule is the SI unit of energy/work. The joule is named after the English physicist James Prescott Joule.
How many joules of energy are in 1 kWh?
3.6 million Joules If you use one kilowatt of power for an hour, you have used 1 kilowatt-hour, abbreviated kWh, of energy. One kilowatt-hour is equivalent to the energy of 1,000 joules used for 3,600 seconds or 3.6 million Joules. In equation form: 1 kWh = 3.6 million J.
What is the SI unit for energy?
joule The SI unit of energy/work is the joule (J), named for English physicist James Prescott Joule (1818 – 1889).
How do you find joules in chemistry?
Then, in terms of SI base units a joule is equal to a kilogram times meter squared divided by a second squared (kg×m2s2) ( kg × m 2 s 2 ) . Another common unit of energy that is often used is the calorie (cal), which is equivalent to 4.184 J.
