Centripetal Force: Mass, Speed, Frequency, Radius

AI Thread Summary
Centripetal force is defined by the equation F = mv²/r, indicating that it is directly proportional to mass (m) and speed (v), while inversely proportional to the radius (r) of the circular path. As mass or speed increases, the required centripetal force also increases. Conversely, increasing the radius results in a decrease in centripetal force. The relationship can also be expressed using frequency (f) and angular frequency (ω), leading to alternative formulations like F = 4π²mr f². Understanding these relationships is essential for analyzing the dynamics of rotating objects.

hello

do any of u guys knw what is the relationship between the centripetal force and frequency, mass, speed, and radius of a rotating object?

thx a bunch :-p

{Mass} = m
{Speed} = v
{Radius} = r
{Frequency of Rotation (in Hz)} = f
{Angular Frequency (in radians/sec)} = ω = 2*π*f

{Centripetal Force} = m*v2/r
OR:
{Centripetal Force} = m*(2*π*r*f)2/r = m*r*(2*π*f)2 = 4*π2*m*r*f2
OR:
{Centripetal Force} = m*r*ω2

Hi there! The relationship between centripetal force and the other factors you mentioned is described by the equation F = mv^2/r, where F is the centripetal force, m is the mass of the object, v is the speed of the object, and r is the radius of the circular motion. This means that the centripetal force is directly proportional to the mass and the speed of the object, and inversely proportional to the radius. As the mass or speed of the object increases, the centripetal force required to keep it in circular motion also increases. On the other hand, as the radius of the circular motion increases, the centripetal force decreases. Hope this helps!
 
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...
