it was mentioned in another thread that only inertial forces are frame dependent or relative.
what is an inertial force?
what are the differences between inertial and non-inertial forces?
and most importantly:
why inertial forces are frame dependent while other forces are not?
i tried...
i think you are missing a fundamental point here.
when youre setting on your chair; your weight pulls you down, and the normal force exerted on you by the chair pushes you up, which means that; these two forces share a common line of action (in opposite directions), and if they are not equal...
what is the physical meaning -and nature- of heat in the molecular scale?
how can molecules emit heat in forms other than EM radiation?
i used to think of thermal energy of matter as the vibrational (kinetic) energy of the atoms/molecules that make up the matter. yesterday i was reading about...
@MikeGomez
"In your examples it might make more sense to say that the gravitational potential at the surface of the Earth (your rocket) is zero. Then the gravitational binding energy is negative, ..."
"Then, after you have overcome the binding energy and the rocket is in space, your...
@Bill_K, may you please explain further; and consider the following arguments:
"Binding energy is the negative of the potential energy"
do you mean that the sum of the two energies is equal to zero?
and consequently they have the same magnitude?
so they would be 100% corelated to each other and...
i think i don't understand the nature of "Binding Energy" very well, and i have a very significant question
what iam really intersted in; is the nuclear binding energy, but i think (hopefuly iam right) that it has the same physical nature (NOT origin) as atomic and molecular binding energies...
@Simon Bridge - yes all replies were useful to me, thank you all
but i still wonder about something; in the field of wireless communications (analog and digital); the information is always carried by a sinusoidal wave (called the carrier, and MUST be sinusoidal) by means of modulation (in...
why all EM waves are sinusoidal ?
or this is not true at all, i.e., EM waves of other waveforms do exist ?
the above 2 questions are among the most vague in classical EM theory, of which i studied many topics in collage as an electrical engineering student, and i liked the subject so i kept...
