AI Thread Summary
Energy is defined as the capacity to perform work or apply force over a distance, rather than being a standalone physical entity. The discussion revolves around the concept of energy in its "pure state" and its ability to transform between forms, such as kinetic and thermal energy. Critics argue that the inquiry lacks a solid foundation in physics, while others emphasize the importance of exploring different perspectives on energy. The conversation highlights the challenges faced by students in grasping complex scientific concepts and the need for constructive dialogue. Ultimately, understanding energy requires recognizing its relationship with the systems that contain it.

What is energy actualy in a pure state and why can it change form (kinetic to heat. Ect) if its not particles.

What do you mean by "pure state"??Does it have to do with statistical ensembles??

ignore whatzzupboy...here is what he send to me in the private mailbox


I am only a freshman and as I have already stadted in my alpollogy thread it was a physics project, we were told to make a theory and show full effects of it and how it would be proven, that I turned into a physcology project, to show how when somebody who knows nothing of what they are talking about trys to make them sound intellegent, in this case by a theory that if correct changes parts of physics, cause the people around them to act.
Sincerly,
Mathew

FYI: My physcology teacher say it looks like I;m going to make an A on. So thank you truly and fully.

Why are you posting all these silly threads?
Why don't you make an effort of learning physics&math, rather than slide into crackpottery?
 
Alright look
1) I'm not a crack pot I to school to hear that not ONLINE
2) It was A simple question so get off my case
3) Why is it that the WE, as human civ., are so stubbor to look at things from a different persective when offten time it is tere that the right answer is found, which by the way is what I am doing looking at te world through a dif. perspective.

Now, if you please can you pease just answer my question and stop crittisizing me, or is itthat you have nothing better to do then to critize a 15 year old freshman boy!

This is not a bad question, actually. Energy is defined as the measure of a thing's ability to apply a force over a distance. It is not a physical quantity in itself. It does not exist separately and apart from the 'thing' that contains energy.

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...
