I was never good at physics. You can help!

So, I'm stuck at a level in Portal where in order to progress, I need to jump off a cliff (into a portal) in order to come out jumping as high as possible on the other side.

My question is this: Do you gain more momentum by
a) pencil-dropping into a portal close to the base
or
b) jumping on an angle into a portal some distance from the base?

Whichever it is, I need to figure out how to get that extra edge. I'm coming up just barely too short every time.

-H

EDIT: To help, here's a cheap little diagram:

1. Jump into hole.
2. Come out of hole full-force
3. Shoot next platform with previous color portal at apex of jump
4. Come out of new portal instead, repeat 3

That continues for about 4 platforms or so.

I wrote another response that hopefully didn't get mailed to you because I realized it might spoil a puzzle. It's possible that neither a) nor b) is faster and you need another way to generate momentum.

I saw the other one, but it didn't spoil anything. =)
I'm on level 18, and there's really no way to double-fall in this room. =/

Look around while you're falling up and down on the last platform pair. I did this room the exact same way, but you might be missing a set of openable squares to get to the last platform.

*hugs* Glad you're having fun with this!

What she said - the very last platform can't be reached by just getting above it and slapping it with a portal like the first few, you have to look around up there and see the trick.

It's not the last one! It's the stupid third one. I can easily get from platform a (the one at ooze level) to platform b, but from b to c is where I'm stuck. I never get high enough to see the top of c, never mind shoot it. =(

Pencil-dropping is the safest bet, as while you do get more momentum by jumping to the orange portal, the risk of overshooting is pretty massive.

Wait wait wait, I know how this one works. Before you start doing the jumpy stuff, look carefully around the room. You're going to want a "head start" before going at it.

Having not played the game yet (because my PC isn't beefy enough), I have to guess... Fall into 1, but come out behind where you started instead of where you're going. Fall into 1 again, but while you're falling from your new higher apex, put the second portal where it needs to be.

Repeat.

Due to there being sections of walls/floors that I can't portal-ify, it won't work that way. =/
