Yeah I agree that static friction behaves this way. I guess I should have been more specific but kinetic friction is primarily what I'm interested in for this case. Kinetic friction does rely on velocity because it opposes the velocity vector, whereas static friction just opposes the net force...
Right but why does the friction force stop pushing when the object comes to rest? It has to depend on velocity to some extent. It may be that it has a constant value which points in the direction opposite of the velocity vector (which would be a zero vector when velocity is zero) but is still...
If friction on a surface were independent of velocity than an object would continue sliding forever if you gave it an initial push that were stronger than friction..? Or it would first cause it to stop, then turn it around and accelerate it in the other direction which is also clearly not the case
Similar to friction, i.e. in the case of friction the maximum value is the coefficient of friction multiplied by the normal force. The friction opposes all motion however it can only exert that certain maximum force so when a force larger than that is put on the object the object will still...
Russ Waters is correct. The open air has no restrictions on its ability to flow other than air pressure. Therefore there would be much more airflow between the two locations without putting a pipe in place than would actually flow through the pipe. So you could generate more energy by putting...
I'm trying to simulate the following situation:
Two bars are attached to each other at one end by a device which controls the angle between them. The opposite end of each bar (the end not attached to the device) is subject to a resistive, motion-opposing (friction-like) force, each with an...
