Question

What does (J) mean in Physics I need within a hour

Answer 1

It typically stands for Joules, which is a measurement of energy. 1 Joule = 1 Newton*meter = 1 kg*m^2/s^2.

Answer 2

Joules.



It was named after James Prescott Joule for his work on the relationship between heat, electricity and mechanical work.



One joule is the work done, or energy expended, by a force of one newton moving an object one meter along the direction of the force. This quantity is also denoted as a Newton-meter with the symbol N·m. Note that torque also has the same units as work, but the quantities are not identical. In elementary units:





One joule is also:



The work required to move an electric charge of one coulomb through an electrical potential difference of one volt; or one coulomb volt, with the symbol C·V.

The work done to produce power of one watt continuously for one second; or one watt second (compare kilowatt-hour), with the symbol W·s.

Answer 3

Joule



A 50 watt light bulb uses 50 joules per second of energy.



It takes 4.184 joules to heat up 1 gram of water by 1 degree C.

Answer 4

J means joules. It's units for energy, electricity and work.



When your units work out to be N * m you convert it to Joules.
