When does Force of Friction = Fnet

AI Thread Summary
The force of friction equals the net force acting on an object only when friction is the sole force present. To provide a meaningful answer, specific details about the scenario are necessary, as the question posed is too vague. If a force is applied to an object, the frictional force will match the applied force until certain conditions change. Without a clear context, the discussion remains superficial and cannot delve deeper into the mechanics involved. Understanding the specific situation is crucial for a comprehensive analysis of the forces at play.

Just need to know, when does Force of Friction = Fnet

This question is far too vague. If you want homework help, you're going to have to post a specific homework problem with details.

That having been said, it's obvious that the force of friction acting on an object is equal to the net force acting on that object IF that friction force is the only force present. It's sort of a case of ask a silly question, get a silly answer.
 


If I'm understanding your question correctly, if you you have a block on a surface and you apply a force to the side of the block the force due to friction will equal the applied force until what happens?
 


You can certainly speculate as to what his scenario is, but unless he tells us, we can't help him. I was trying to drive home the very important point that the question that he was asking was ill-posed. At the very least, it was insufficient, because it has only a trivial answer, which I gave him. We can't elaborate because there is no universal way of doing so (the answer is entirely situation-specific).
 
Thread 'Minimum mass of a block'

Thread 'Minimum mass of a block'

Here we know that if block B is going to move up or just be at the verge of moving up ##Mg \sin \theta ## will act downwards and maximum static friction will act downwards ## \mu Mg \cos \theta ## Now what im confused by is how will we know " how quickly" block B reaches its maximum static friction value without any numbers, the suggested solution says that when block A is at its maximum extension, then block B will start to move up but with a certain set of values couldn't block A reach...

Thread 'Electric field due to charges between 2 parallel infinite planes'

TL;DR Summary: Find Electric field due to charges between 2 parallel infinite planes using Gauss law at any point Here's the diagram. We have a uniform p (rho) density of charges between 2 infinite planes in the cartesian coordinates system. I used a cube of thickness a that spans from z=-a/2 to z=a/2 as a Gaussian surface, each side of the cube has area A. I know that the field depends only on z since there is translational invariance in x and y directions because the planes are...
