A joule is defined as the work done when a force of 1 newton is applied to an object over a distance of 1 meter. Therefore, the correct definition from the options you've provided is:

**It is the work done when a force of 1 newton is applied to an object for a distance of 1 meter.**

To summarize, 1 joule (J) is equal to 1 newton (N) of force applied over a distance of 1 meter (m) in the direction of the force.
