Conceptual Physics. Trying to understand vectors.

I wanted to take summer classes, but my goddamn high school says that they're only for kids that have failed classes and have to retake them.

And say one set of the ropes is somewhat rotted, or has fewer strands in it. Then you can't be sure.

Holy shit I'm sleepy.

Ok so now I'm working on inertia and I have come across this problem.

I want to see if I am explaining it right, but it is still relevant to the chapter.

"In an orbiting spacecraft, you are handed
two identical closed boxes, one filled with
sand and the other filled with feathers. How
can you tell which is which without opening
the boxes?"

Now since you are in space, determining the object's weight would very difficult since the gravity from planets are extremely weak. So that is out of the option. If you gently toss them away at the same time, provided that your space station has enough room, you could determine which one has sand because of the object's [b]inertia[/b]. That means the box of sand which contains more mass than feathers will come to a quicker halt as compared to the box of feathers correct?

Hey is there a Physics Megathread by the way?

The only thing I'm questioning is the number of people posting answers without any knowledge of physics.

yes. the one with feathers should stop faster due to the equal force of air resistance against the lower momentum

[QUOTE=CabooseRvB;23369063]So that means you can't have an infinite tension???[/QUOTE]

The guitar string will always sag.

and the tension on the girls swing would make it more likely to break.
