If gravity isn't getting any stronger, why wouldn't my speed remain constant when jumping out of an airplane? | Gravity is a force acting upon you. It doesn't just 'yank you' once and then quit. It continues to pull the entire time you are falling. So there is a net force downwards for the entire period of your descent, which causes you to accelerate. It's only when you reach terminal velocity that there is a counter force, effe... |
Do submerged submarines rock or bob? Why, why not? | Most of the wave action is on the surface. So the bobbing and rolling that surface ships experience is minimal.

Why doesn't solid material, when it breaks simply connect back together? What kept it together that is gone now? | As soon as you break molecules apart they immediately want to stick to something, and they'll take anything that fits.

With metals it's ge... |

How do car keys wirelessly lock/unlock only your car? | They transmit a digital code which only your car responds to.

What exactly is a neutrino? | It's a kind of fundamental particle. Neutrinos are very small, even compared to most other fundamental particles.

So if Einsteins theory of GR toppled Newton's theory of gravity and its effect on matter, making it seem almost incorrect, why is it still being taught at school as basic fundamental physics? | Newton's theory was a very very good approximation. And it still is. It's not like the laws of physics have changed since then. General Relativity is probably wrong too. But it's an even better approximation than Newton's theory is. It's also more complicated, so if you don't need it then using it is a waste of time. |
Why do people (Soldiers, Police, Government Agents) always seem to duck when approaching a helicopter? | Because the rotor disc of a helicopter isn't fixed.

With the helicopter on the ground, and the collective neutral you can articulate ... |
Why do raptors put up with harassment from small territorial birds? | Because it's hard to win a fight 1 vs. many. Especially in the air.

The Google stock drop. Why it happened, what it means, and what are the consequences. | Google failed to meet expectations for how much money they were going to earn this quarter.

This is a buying opportunity, and when they po... |
Why turbulence on an airplane, even the bigger bumps, aren't something to worry about while flying on an airplane | So long as you're going to a sufficient speed, the wings will create a pressure differential buoying you up.

Why have people freaked out so much that Valve+Bethesda wanted to take 75% of mod revenue, but not that Valve takes 30% from an indie game that someone entirely made themselves? | Honestly, part of it is mass hysteria and part of it is this is the first time a lot of otherwise ignorant people have stopped and thought about the fairness of how Steam goes abouts its business.

How did the first person to interact with a new language go about learning / interpreting that language? | To put it simply I imagine it happened through immersion like [this scene from The 13th Warrior] or the way it's portrayed in any other movie: pick up object and say what it is slowly, then the person whose language you're struggling to learn says their word for it, then mimic what they said, repeat until fluent. |

Why do a movie theater employees enter a movie a few minutes after it begins with a clip board, stands to the side for a few minutes, then leaves again? | It may actually be the projectionist, I used to work in projection and we would often nip into the screen to check the audio as the feature starts.

How is it cheaper to lobby a foreign government, permit and build 1400 miles of pipeline and assume risk and liability of it than for Canada to refine their own crude? | Because Canada has little to no refining capacity as it is.

Do Islamic women also believe in the notion of having 72 virgins in heaven? | The whole "72 virgins" thing is not necessarily a mainstream Muslim belief.
