Web16 nov. 2024 · In a first course in Physics you typically look at the work that a constant force, F F, does when moving an object over a distance of d d. In these cases the work is, W =F d W = F d. However, most forces are not constant and will depend upon where exactly the force is acting. So, let’s suppose that the force at any x x is given by F (x) F ( x). Web20 apr. 2016 · You see that the work done is negative. However if the force and displacement were both in the same direction, the angle would have been zero and cos ( 0 ∘) = + 1. Work done would have been W = F d or a positive value. Hence positive work would have been done by the force. do great pyrenees pant a lot
