For a constant force, the force **F**
can be taken out of the integral, to get the result

For our course we just define work
in the simplest possible way: *W*_{F} = F_{x}
Δx.

We can write *W _{F} = *∫

For our course just remember that the work done by any force is zero unless the force has a component along the direction of motion of the object.

No work is done either by the force
**n** or the force *m***g**.

For the fundamental forces of
nature, such as gravity, the work done by or against the force
is **independent of the path taken.**
