    Force Friction
AI Thread Summary
To find the work done overcoming friction, two methods can be used. The first method involves calculating the work using the formula Wf = Ff x d, where Ff is the frictional force and d is the distance over which it acts. The second method requires determining the wasted work, which can be more complex and may involve analyzing energy loss in a system. Clarification on how to calculate wasted work is sought, indicating a need for further assistance. Understanding both methods is essential for accurately determining the work against friction.

Homework Statement


There are two ways to find how much work is done overcoming friction. Please describe both methods.


Homework Equations


Wf = Ff x d

The Attempt at a Solution


I know one method-- you have you know the force overcoming friction. You would use (Wf = Ff x d). But i really cannot figure out the calculation that can be done to find wasted work. can someone PLEASE help me?! thank you so much!

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...
