AI Thread Summary
Static friction is greater than kinetic friction on an inclined surface because static friction must overcome the initial resistance to motion. When a stationary object, like a heavy box, is pushed, it experiences higher static friction until enough force is applied to initiate movement. Once the object is in motion, kinetic friction takes over, which is typically lower and requires less force to maintain movement. This difference in friction types is due to the molecular interactions between surfaces, which are stronger when stationary. Understanding this concept is essential for grasping the mechanics of motion on inclines.

Hey, i was just wondering if anyone can explain why static friction appears to be higher then kinetic friction on a stationary object, which is on an incline?

~thx:confused:

As far as i know static friction will always be larger than kinetic friction. I can't explain the precise physics behind why that is true but imagine this situation.

Imagine there is a very heavy box on the floor that you want to push. When you try to push this box it won't budge because of the (static) friction between the floor and the box. Once you apply enough force you get the box moving and if you keep it moving you would notice that the (kinetic) friction force feels much less.

I hope this is the answer you are looking for. It is logical that static friction will be more than kinetic if you think about it. I'm sure you tried to push something that wouldn't budge, but once you got it moving it was much easier to push it.
 
thanx, that helped a lot :)
 

Thread 'Errors and significant figures'

I multiplied the values first without the error limit. Got 19.38. rounded it off to 2 significant figures since the given data has 2 significant figures. So = 19. For error I used the above formula. It comes out about 1.48. Now my question is. Should I write the answer as 19±1.5 (rounding 1.48 to 2 significant figures) OR should I write it as 19±1. So in short, should the error have same number of significant figures as the mean value or should it have the same number of decimal places as...

Thread 'A cylinder connected to a hanging mass'

Thread 'A cylinder connected to a hanging mass'

Let's declare that for the cylinder, mass = M = 10 kg Radius = R = 4 m For the wall and the floor, Friction coeff = ##\mu## = 0.5 For the hanging mass, mass = m = 11 kg First, we divide the force according to their respective plane (x and y thing, correct me if I'm wrong) and according to which, cylinder or the hanging mass, they're working on. Force on the hanging mass $$mg - T = ma$$ Force(Cylinder) on y $$N_f + f_w - Mg = 0$$ Force(Cylinder) on x $$T + f_f - N_w = Ma$$ There's also...
