The third in my series of puzzles inspired by real physics.

Momentum is related to mass and velocity and is conserved during a collision (except when friction gets invovled, greatly complicating things, which is why physics professors accross the world use the phrase "ignoring friction" on a regular basis). When two objects collide, momentum is transferred between them but the total momentum stays the same.

I've modded my PTI editor so that there is now a placement helper above the faith plate. This greatly reduces the chance that the cube will hit the edge of the portal on its way through.

Way too similar to lab 2. The mechanic is pretty the same. Still fun and nice map design. 6.5/10

AWESOME map. One that makes you feel like your a genious or just a shmuck with a crazy stroke of luck...

Liked this one, too! I like the way you think-incorporate these ideas into bigger puzzles, and they'll be excellent.

Simple, yet elegant.

OK, so you re-used cube collisions from Lab 2, but it was still interesting. I appreciate how hard it must be to make this work. If you could just combine your novel features with more challenging puzzles ...

Nicely done with the chamber.

Good puzzle, but again not really seeing the theme. Figured there'd be something with speed/velocity for momentum.

Pretty easy, but really clever and funny!

Small update! The target above the faith plate will now automatically position a portal that you shoot on it, so you shouldn't have to reset and retry the cube launch so many times.

I could have done with a little less walking to reset things when the cube took a bad bounce and fizzled or if the cube hit the side of the portal on the way through.
