When does Force of Friction = Fnet

In summary, the conversation discusses the relationship between force of friction and net force, with the conclusion that in a scenario where the force of friction is the only force present, it will equal the net force acting on the object. However, without further details or a specific problem, providing more information or help is not possible.

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).
 

1. What is the force of friction?

The force of friction is a resistive force that opposes the motion of an object. It is caused by the interaction between the surfaces of two objects that are in contact with each other.

2. What is the net force?

The net force, also known as the resulting force, is the vector sum of all the forces acting on an object. It determines the direction and magnitude of the object's motion.

3. When does force of friction equal net force?

The force of friction equals the net force when an object is moving at a constant velocity. In this case, the forces acting on the object are balanced, and the net force is equal to zero.

4. How does the force of friction affect motion?

The force of friction can either increase or decrease the speed of an object, depending on the direction of the force. If the force of friction is in the opposite direction of the object's motion, it will slow down the object. If it is in the same direction as the object's motion, it can increase its speed.

5. What factors affect the force of friction?

The force of friction is affected by the type of surfaces in contact, the roughness of the surfaces, and the force pushing the surfaces together. It also depends on the normal force, which is the force exerted by a surface on an object in contact with it.
