Total mechanical energy of a system

AI Thread Summary
The total mechanical energy of a system is not equally divided between kinetic energy (KE) and potential energy (PE). While both forms of energy contribute to the total mechanical energy, their ratio can vary significantly depending on the system's state. An object can possess either potential or kinetic energy without having the other, indicating that they are not inherently balanced. The relationship between KE and PE is dynamic, with energy transforming between the two forms rather than being fixed. Therefore, the notion of an equal division of energy is incorrect.

is it true that the total mechanical energy of a system is equally divided between kinetic energy and potential energy?

That is the definition, yes, but you should definitely realize that there are many more forms of energy in real life, but they just get messy and complicated if you try to introduce them into simple problems.
 
I don't see how that could be. The reason we keep track of potential energy is because it can change into kinetic energy, and vice versa. The ratio of kinetic to potential energy is constantly changing.

EQUALLY being the key word here...The answer is no. Think about it. An object can have potential but no kinetic energy and vice versa. You my possibly be meaning that KE and PE are combined to make the entire energy in the system...but it is not split evenly between the two.

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...
