hello I would like to know the formula for force? 
Force Formula: Find Out How to Calculate Force
AI Thread Summary
The discussion centers on the various types of forces and their calculations, specifically highlighting the formula for gravitational force. The formula for gravitational force is expressed as F = mg = GMm/r, where M represents the mass of the Earth and r is the distance from the Earth's center. Participants inquire about different forces, including those from springs, electricity, pressure, friction, air resistance, magnetism, and nuclear forces. The effects of force, such as changes in momentum, acceleration, work, and compression, are also mentioned. Understanding these concepts is essential for applying the force formula in various scientific contexts.
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...
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
$$T + f_f - N_w = Ma$$

This problem is two parts. The first is to determine what effects are being provided by each of the elements - 1) the window panes; 2) the asphalt surface. My answer to that is
The second part of the problem is exactly why you get this affect.
