For the sake of simplicity, let’s say you have negligible mass, while the two masses, m1 and m2, have equal masses and sizes. Everything is moving at some velocity in a vacuum.

When the two masses are touching, the Centre of Gravity is midway between their Centres of Mass, which in this scenario would mean it is where they touch.

When you pick up m2, an equal and opposite force would push m1 away. Because they both have equal mass, both would end up the same distance away from the CoG. If you lifted m2 on your head, the CoG would be right at the middle of your height.

For as long as you’re holding m2, your body is resisting the force of attraction due to gravity between m1 and m2. When you drop m2, both it and m1 accelerate towards the CoG. When they meet, the energy you put into lifting m2 would be converted into heat in the collision. From an outside observer, while you were doing all that, the CoG was moving in a perfectly straight line with no change in velocity.

Now, if you instead threw m2 away from m1 faster than its escape velocity, then that would change the velocity. If m1 and m2 weren’t equal in mass and size, the CoG would still be moving in a straight line, but the distance m1 and m2 moves away from the CoG would be proportional to their masses.

Fortunately, with Space Age, Nauvis pollution becomes less of a problem as you have more and more of your manufacturing being done on other planets.

Basically all of hydrogen production is sourced from fossil fuels.

Toxic masculinity makes men go blind and die rather than follow the Golden Path.

We all make mistakes in the heat of passion Jimbo.

Having any mods enabled stops you from getting Steam achievements. A small price to pay for Squeak Through.

The white flag is, per international treaties, a signal you want to communicate with the other side regarding a truce or surrender. It’s not a free “get out of jail” card when you’re retreating.

There are only so many ways you can whip up a population into a genocidal fervour.

Yes, but 50 rounds are more likely to be hit than just 1. And if you put them in a spot that’s going to be shot at a lot, say the turret, you’re less likely to walk away from a penetrating hit.

FN P90’s magazine turns the bullets 90 degrees by turning them with its feed geometry. It kinda looks like a slide for bullets if you squint hard enough. HK G11 uses about as many parts as in an average Swiss watch to do the same thing.
