Here's why:

* Work is defined as the force applied to an object multiplied by the distance the object moves in the direction of the force.

* Formula: Work (W) = Force (F) x Distance (d)

* In this case:

* Force (F) = 1 Newton

* Distance (d) = 1 meter

* Therefore: Work (W) = 1 Newton x 1 meter = 1 Joule

Important Note: The force and the displacement must be in the same direction for this calculation to be accurate. If the force and displacement are at an angle to each other, you need to use the component of the force that is parallel to the displacement.
