Which of the following is the correct statement?
Show answer & explanation
Correct answer: A
Explanation
The correct answer is option 1 i.e. Joule is the unit of work.
The correct statement is: Joule is the unit of work. In the International System of Units (SI), a joule is defined as the amount of work done when a force of one newton displaces an object by one meter. The unit of energy is also the joule, not the watt, which is the unit of power. Joule/second is indeed a unit of power, known as a watt. The unit of power is not joule/newton but is measured in watts.
