Yeah, I am looking for the physical intuitive explanation. Could you possibly expand on the idea of conversation of energy as a reason for mechanical advantage? Thanks

Right, I know that. But why does mechanical advantage occur is what I am trying to get at.

I am having a difficult time understanding the reasoning behind torque. From a textbook I read, However, why is it that it's easier to rotate a door when you are farther from the rotational axis? You are still moving the same amount of mass. Of course, I know that torque = r x F and thus...

Do you have any specific books in mind? Sorry, that's what I meant. I am just having trouble understanding why multiplying the original function by (x/n) can lead to the area under the curve.

I am having trouble figuring out how an integration works. Consider the function, y = x2 . The antiderivative is x3 / 3 or in other words its x2 (x/3). How come multiplying the original function by (x / n) (where n represents the exponent + 1) will lead to the area under the curve. Put in...

Okay I have several questions that have been bothering me for some time now, so bear with me please. How does integration work? Integrating the function f(x) between the bounds a,b finds the area under f(x) between a and b. But how does this work?If my function is f(x) = 2x and my bounds are...

Okay thanks for that. Somewhat unrelated, if you were to, let's say, take a guitar into space. The guitar strings each have their own natural frequency. However if you were to pluck one of the strings, would a frequency (and corresponding wave) be produced? Doesn't sound, which is produced...

What does the natural frequency of an object depend on? Whenever I try to look this up, I usually read that the natural frequency depends on "intrinsic" properties or a "variety" of factors. Is the natural frequency independent for each object/is there any universal factor the natural...

Thanks a lot. Is the energy we generate from food the sole source of energy? Or does other factors play a role, such as friction from movement or absorption of energy from the sun? If all these factors are prevalent, how does one determine the energy of an object? For example, if I wanted to...

Question regarding the emission of infrared radiation, for personal knowledge. Why do humans emit infrared radiation? Is it because it just so happens that the energy humans absorb (from sunlight)/ the energy humans produce just so happens to correlate to the frequency of infrared, as...
