Difference between electric, electrical and electrostatic

AI Thread Summary
Electric, electrical, and electrostatic forces have distinct meanings in physics. "Electric" refers to forces related to electric charges, while "electrical" pertains to systems or devices that utilize electricity. "Electrostatic" specifically describes forces between stationary charges, indicating a lack of movement or change. The discussion clarifies that electrostatic force applies to point charges, whereas electrical force relates to changing electric fields. Understanding these differences is crucial for accurate application in physics.

"static" implies not changing. That would not necessarily be true for the first two terms...

So for point charge it provides electrostatic force while changing electric field gives electrical force?
Thanks for replying!

That sounds accurate to me. :smile:
 
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'
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...
