The 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. 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:
(1)
When they are not parallel, both directions form an angle, let's call it . In that case the expression to calculate the Work is:
(2)
For example, in order to pull the bicycle out of the garage, you have to apply a force along the distance to overcome the resistance of the weight of the bicycle.
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:
