What if the light sources are no longer attached to the train, but attached to the train station. Let's imagine that the train passes the two lights in such a way that they both are triggered to flash when one of the lights is in front of me, and one behind me, both equally distanced from me...

Thats what i thought. Will I also see both flashes at the same time regardless of the inertial velocity? (i.e the velocity before i flip the switch)

So i will not see the two lights flash at the same time, regardless of my velocity? Im totally confused now. First yes, then no?

For instance accelerated frames of references?

I am standing in the middle of a train. There are two lightsources attached to the train. One in the front, and one in the back. Both aimed at me, both with the same distance from my position in the train. No matter how fast the train is moving, i will always stay equally distanced to them. The...

a is just a constant.

Lets say F=-av If i integrate this, isn't it soley dependent on the start and end point? And thus, its conservative..?

If F is a force acting on a atom and is dependent on the velocity of the atom. Is the force conservative?

Why would the same change in momentum results in a different change in velocity?

Is a different because of length contraction?

Lets assume the object is traveling in the x-direction. Ive been told that any force on the object in the x direction is given by F = maϒ3. And that any force in the y or z direction is given by F = F = maϒ. Why is there a difference between the x direction and the y, z direction?

then i mean inflection!

first of all... if i start with y'(x) = 6y(x) -(y(x))^2 and try to find y''(x) i get... y''(x) = (6y(x))' -((y(x))^2)' y''(x) = 6y'(x)x' - 2y(x)y'(x)x' y''(x) = (6- 2y(x))(y'(x)x') If y''(x) = 0 the y'(x)x' = 0 or 6- 2y(x) = 0 Is this even correct ?

When i write turning point, i mean where the function changes from concave to convex, or vica versa. In my native language we call this point a turning point.

i have to differentiate y''(x) = 6 y'(x) x' - 2 y(x) y'(x) x' ?
