When two substances have the same temperature, the particles have the same average kinetic energy, right? So why is it that some substances take more energy to increase the temperature one degree even if the increase in average kinetic energy is the same? I'm referring to specific heat...

Ok so entropy cannot be destroyed, right? So let's say you have a reaction that decreases entropy (s<0) but it also is exothermic (h<0) and that overpowers the entropy decrease so it is spontaneous (ie h-ts=g<0). If that happens, where does the entropy go?

At only one point is GM/r^2 exactly equal to 9.8. However, since r only changes slightly with respect to its value at heights we experience, for all intents and purposes, g=9.8m/s^2.

Are photons capable of interacting with particles with no charge. And if not, is it possible that that's the reason dark matter has so far eluded detection: because it has no charge?

Is there a smallest possible amount of energy? Like, one where all energy quantities in the universe are a multiple of it and the only way to have less energy is to have none at all? If a photon had that energy, it would be the longest possible EMR wavelength. Or can energy be divided...

So if I understand you correctly, the second law of thermodynamics does not necessarily dictate an increase in disorder, but rather an increase in possibilities of what the system can be, thereby increasing the likelihood of a disorderly state.

The second law of thermodynamics essentially states (paraphrased) that the universe always moves from order to disorder (increase in entropy). The problem I have with this, though, is that there is no thermodynamic definition to disorder that I am aware of. Is there such a thermodynamic...

So if I understood this correctly, that means when a mass is shrunk to its Schwarzschild radius, the escape speed is the speed of light at the surface of the object.

The Earth was impacted by a planet-sized object very early in its lifetime. This expelled a lot of matter that formed a ring like Saturn's. Because the matter was far enough away from the Earth to form a moon, that's exactly what it did. So the moon started out moving, the necessary kinetic...

At the point where the object has descended 1m, the spring will be exerting a force of 100N, as will the force of gravity. However, this says only says that the velocity is not changing, not the position. Before reaching the 1m point, the force exerted by the spring would have to have been less...

The force caused by air resistance is given by the equation D=kv where D is the drag force, v is the speed at which the drop is falling, and k is the proportionality constant between them. The force of gravity is given by W=mg where W is the force caused by gravity, m is the object's mass, and g...

An indefinite integral, as you probably know, is merely the antiderivative of a function. A definite integral is the change in the antiderivative's value between the two points equal to the limits. For example, if you have velocity as a function of time and you take the integral from t=0 to t=3...

The Schwarzschild Radius of an object is the length such that if the object is shrunk down that small, the escape velocity becomes equal to the speed of light. That being said, however, the escape velocity of any gravitational body matters where it is measured relative to the center of mass...
