Explanation:
Work
done by a Force
refers to the release of potential energy from a body that is moved by the application of that force to overcome a resistance along a path.
It should be noted that it is a scalar magnitude, and its unit in the International System of Units is the Joule (like energy). Therefore, 1 Joule is the work done by a force of 1 Newton when moving an object, in the direction of the force, along 1 meter:
Now, when the applied force is constant and the direction of the force and the direction of the movement are parallel, the equation to calculate it is:
When they are not parallel, both directions form an angle, let's call it
. In that case the expression to calculate the Work is:
In this case both (the force and the distance in the path) are parallel, so the work
performed is the product of the force
by the distance traveled
. as shown in equation (1).
Hence:
