    Concept Work
AI Thread Summary
The discussion revolves around the concept of energy output by a person when applying force to an object. It clarifies that work done, defined as force multiplied by distance, is often equated with energy release, although the terms are technically different. Participants debate whether energy given out is synonymous with work done, emphasizing that energy is still expended even if the object remains stationary. The conversation highlights the nuances in terminology while reinforcing the relationship between work and energy in physical contexts. Understanding these concepts is crucial for accurately discussing human energy expenditure in various scenarios.

How much energy is given out by one man?
If he applied a F on a object, friction is f, distance is s.
What's the energy given out by him?
 
Physics news on Phys.org
What is your guess??

hint: Work done = Force x Distance
 
What do you mean by "energy given out"? Is that the same as "work done"?
 
I suppose that they are not the same.
As a man is still releasing energy when he is moving a box even the box is still stationary.
 
work done by the man= energy release by the man
the term is different but the meaning is the same...
 

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...
