AI Thread Summary
The discussion revolves around understanding the assignment for a concept quilt on various types of forces, including friction and field forces. Participants suggest that the quilt should include both formulas and descriptive examples for each type of force listed. Normal force is explained as the reaction force from a surface due to an object's weight, which also affects friction. Clarification is sought on contact force and field force, with hints that field forces may pertain to magnetic and electric interactions. Overall, the focus is on providing clear definitions and examples to meet the assignment's requirements.

Homework Statement


Well pretty much i am just starting on my concept quilt and my teacher gave us 9 types of forces that we learn well studied and i need help to understand what she wants me to do.

these are the types:
Coefficient of Friction
contact f
Field F
Force Diagram
Kinetic Friction
Net external force
normal F
static friction
weight


Homework Equations



am i suppose to do only formulas? like "net external force F-ma" or ma i suppose to give an example?

what is contact F and Field F and Normal F?

Can anybodi give me examples i'll be realli grateful!


The Attempt at a Solution



i attempt to try to find examples yet it didn't work so i landed upon here :D

Hard to say what your teacher wants, but I'd provide a formula that has that force and write a sentence describing each. Normal force refers to the force that objects apply as a reaction to some external force (i.e. the floor applies a normal force to me as a result of my weight). I'd also relate normal force to how it affects friction force. Field force may be related to magnetic and electric fields? Contact force is probably more obvious than you think.
 

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...
