I recently trying to learn General Relativity by first scraping the surface on ScienceClic's general relativity playlist, and then I stumbled upon a video where it said that we actually move through spacetime on a constant speed of c, and then I remember about time dilation because how speed on...

I am actually new to differential equation, but I will try to write what I know, please help to correct it: since acceleration get smaller as it get closer to max velocity and become 0 when it get equal or more than max velocity, I think the equation will become look like this(?): ##dv = (a_0 -...

for example, I want to know velocity of a person when time is equal to t, that person start running from 0m/s (t=0s) to max velocity of 1m/s (t=1s). I am thinking that this is like rain droplet that affected by gravity and drag force, where force is directly proportional to its velocity, to make...

in video "Einstein Field Equation - for Beginner!" by "DrPhysicsA" on youtube, in 01:10:56, the christoffel symbol equation is written, then i see in "Physics Videos by Eugene Khutoryansky" video with title "Einstein's Field Equations of General Relativity Explained" in minute 05:02 on how the...

i am new at relativity, it said mass can curve spacetime, does this mean spacetime will curve to a new 5th dimension (1-3 for space dimension, 4 for time dimension)?

thank you very much, that's the keyword, its measured from O's coordinate

since i am new at learning special relativity, i still miss the concept about how thing move in special relativity. In high school, i am doing several problem about velocity addition, and that word always appear. for example: A is moving with velocity vAO relative to O, and B is moving with...

ok, thank you very much

I think this question is not important and rarely noticed, but I'm still curious XD kinetic coefficient of friction is used when the applied force of static friction coefficient is less than than the force that we give, or less than or equal to the force that we give? sry for my bad english
