Finding Work Done by Force (F): Is it Fx or F?

Click For Summary
SUMMARY

The discussion centers on calculating work done by a force (F) and clarifies that the work is determined by the component of the force that is parallel to the displacement. Specifically, the work done is calculated using the x component of the force (Fx) when the displacement is also along the x-axis. The formula for work is defined as the dot product of the force vector and the displacement vector, emphasizing the importance of direction in these calculations.

The question asks.. find the work done by Force (F)...
the answer given was found by the x component of Force (F)... so my question is, is this the work done by Fx or by F?

When dealing with work, the component of force that is parallel to the displacement of the object is used for calculations. Work is equal to the dot product of the force and displacement vectors.
