Hello /sci/. /fit/ here. We seem to have a dilemma. Help us. I'm currently taking physics, but there seems to be a big issue about whether or not the block has momentum depending on which side of the portal you witness this situation occur. So which is it /sci/, A or B?

stop trolling with this worn out bs

completely srs.

B, /thread
Anyone who says otherwise is troll or retard.

>>5398416
you are entirely wrong

>> No.5398439

>>5398423
either A or B is plausible, because the frame of reference for the cube and for the portals are disconnected.

but >>5398405 is right. stop trolling

b is not plausible under any scenario. A is implausible for other reasons. Thankfully we know the answer and it is that the portal acts like a wall.

B is plausible if portals are oneway momentum exchangers.

Let's do a little experiment:
>place cube on floor
>drop hula-hoop around cube

So what happens? Our options are:

a) The cube flies upward with initial velocity equal to the hoop's final velocity.

b) The cube remains on the ground. The hoop obviously transferred its energy into the ground.


Now I ask, what is fundamentally different in the portal scenario?

>> No.5398528

>>5398519
In the reference frame of the hula hoop, the cube appears to have momentum.

So the fundamental difference is the hula hoop is not a portal.
