Explanation:
The Work [tex]W[/tex] done by a Force [tex]F[/tex] 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:
[tex]1J=(1N)(1m)=Nm[/tex]
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:
[tex]W=(F)(d)[/tex] (1)
Where [tex]d[/tex] is the distance traveled by the object.
In this case:
[tex]F=20N[/tex] and [tex]d=5m[/tex]
Hence:
[tex]W=(20N)(5m)[/tex]
[tex]W=100Nm=100J[/tex] >>>>This is the work
