Definition The work done by a force is defined to be the product of component of the force in the direction of the displacement and the magnitude of this displacement. Formula Work can be calculated by multiplying Force and Distance in the direction of force as follows W = F × d Unit Th...
Note that if F is constant, the integral evaluates to F⋅(b−a)=F⋅d,F·(b−a)=F·d, which is the formula we stated at the beginning of this section.Now let’s look at the specific example of the work done to compress or elongate a spring. Consider a block attached to ...
