OVERHEARD: "If you fell through a hole to the other side of the earth, wouldn't you get launched like really high from all the momentum?"

  1. We also only like working in a vacuum. If you could just suck all the air out of that hole, that'd be pretty helpful.

    1. the answer is trivial anyway, all the energy you gain going down is lost going back up, so the answer is no, you'd be lucky if you even made it back out the other side

    2. If my intuition is correct, you would just oscillate back and forth losing force to friction until you stabilize in weightlessness at the center.

    3. What 1b said. We did a similar problem in 124 with Mann. You keep oscillating back and forth perpetually if assuming frictionless vacuum.

    4. In reality, you would lose some energy to air resistance every period of oscillation, and eventually end up in the centre of the planet. Sucks to be you.

    5. In reality you would melt long before getting to the center...

  2. Depending on where you dug the hole, you'd probably crash into the side of it well before you got anywhere from the rotation of the planet. They did this experiment with a bowling ball and a reaally deep mine shaft, bowling ball never made it to the bottom.
