    Friction Time
AI Thread Summary
Time can influence the static and kinetic friction between surfaces, with longer stationary periods potentially increasing static friction due to bonding effects. Certain surface combinations may develop stronger interactions over time, making it harder to move an object after extended contact. The discussion highlights that this effect varies significantly depending on the materials involved, as not all surfaces exhibit the same frictional properties. While some surfaces may bond more effectively, others do not show significant changes in friction with time. Overall, the relationship between time and friction is complex and material-dependent.

I was just wondering what effects would time (time spent stationary) have on an objects static friction max, or its kinetic friction (constant). Like would an object that was on a surface for 5 seconds be harder to move than if it were on the surface for 1 hour? Why Why not?
Thank You:smile:

P.S. Not glue!

Depends on the surface. A surface of super glue set onto a plastic table would have an increase of the static co-efficient over time.
 
Some combinations of surfaces involve a form of bonding (not glue), which will increase static friction.

Ha ha. I gave an extreme example, but yes other surfaces can bond over time though I am not sure you can't classify those surfaces as very inefficient glue.
 

Thread 'Is calling fictitious forces "not real" just about terminology?'

Hi there, im studying nanoscience at the university in Basel. Today I looked at the topic of intertial and non-inertial reference frames and the existence of fictitious forces. I understand that you call forces real in physics if they appear in interplay. Meaning that a force is real when there is the "actio" partner to the "reactio" partner. If this condition is not satisfied the force is not real. I also understand that if you specifically look at non-inertial reference frames you can...

Thread 'Derivation of Hamilton's Principle: Questions'

I have recently been really interested in the derivation of Hamiltons Principle. On my research I found that with the term ##m \cdot \frac{d}{dt} (\frac{dr}{dt} \cdot \delta r) = 0## (1) one may derivate ##\delta \int (T - V) dt = 0## (2). The derivation itself I understood quiet good, but what I don't understand is where the equation (1) came from, because in my research it was just given and not derived from anywhere. Does anybody know where (1) comes from or why from it the...
