WebDec 27, 2016 · My notes say that if F is conservative (i.e. F = ∇ f) then curl ( F) = 0. But I feel this is not quite right. There is a theorem that says that if f ( x, y, z) has continuous second order partial derivatives then curl ( ∇ f) = 0. (I'm fine with this theorem, it makes sense.) Obviously the 'proof' for my question is curl ( F) = curl ( ∇ f) = 0 WebIf a force is conservative, it is possible to assign a numerical value for the potential at any point and conversely, when an object moves from one location to another, the force …

WebFeb 20, 2024 · If only conservative forces act, then Wnet = Wc where Wc is the total work done by all conservative forces. Thus, Wc = ΔKE. Now, if the conservative force, such as the gravitational force or a spring force, does work, the system loses potential energy. That is, Wc = − ΔPE Therefore, − ΔPE = KE or ΔPE + ΔKE = 0. WebFeb 20, 2024 · Examine all the forces involved and determine whether you know or are given the potential energy from the work done by the forces. Then use step 3 or step 4. Step 3. If you know the potential energies for the forces that enter into the problem, then forces are all conservative, and you can apply conservation of mechanical energy simply in terms ...
