Assuming a surface with no friction in space (you get the idea), I push/kick/give a 1kg block on this horizontal plane a force of 1N. It would start to accelerate in the direction i pushed it with at a rate of 1m/s² forever until another force acted upon it. So far so...

I'm trying to close in on a more intuitive way of understanding tensors. For some reason, they've always held an aura of mystique for me, may be also their similarity to the word "tense" has meant that I've never really warmed to the many defintions and explanations available. So, in many...

can continuously changing magnetic field increase the temperature of a magnetic material?

my hypothesis is that the continuously change of magnetic field will cause a continuous change in orientation of the atoms of the magnetic material and thus it will increase the thermal energy of...

I have a question about the meaning of this term "translating frame". Lets consider x-y axis fixed in one place. Now we can construct a unit circle with origin at (0,0). Now I am going to construct another frame of reference with origin at (1,0) (in x-y system). I will let...

I just had a question regarding artificial satellites:

From what I understand, satellites are able to enter into a lower orbit by reducing their velocity, which makes sense because of V=2*pi*r/T

However, decreasing radius should also increase Fg and thus acceleration and thus...
