Even if you imagine doing them separately, the acceleration of the Earth cannot be calculated based on just a singular force unless you assume nothing else is exerting a force on the Earth during the process of the fall. For a realistic model, this is a bad assumption. The Earth is a massive system which interacts with a lot of different systems. The one tiny force exerted on it by either the feather or bowling ball has no measurable effect on the motion of Earth. This is not just a mass issue, it’s the fact that Earth’s free body diagram would be full of Force Vectors and only one of them would either be the feather or bowling ball as they fall.

As for my second point, I understand your model and I am defining these references frames by talking about where an observer is located. An observer standing still on Earth would measure the acceleration of the feather or bowling ball to be 9.81 m/s/s. If we placed a camera on the feather or bowling ball during the fall, then it would also measure the acceleration of the Earth to be 9.81 m/s/s. There is no classical way that these two observers would disagree with each other in the magnitudes of the acceleration.

Think of a simpler example. A person driving a car towards someone standing at a stop sign. If the car is moving 20 mph towards the pedestrian, then in the perspective of the car’s driver, the pedestrian is moving 20 mph towards them. There is no classical way that these two speeds will be different.

This argument is deeply flawed when applying classical Newtonian physics. You have two issues:

1. Acceleration of a system is caused by a sum of forces or a net force, not individual forces. To claim that the Earth accelerates differently due to two different forces is an incorrect application of Newton’s second law. If you drop a bowling and feather in a vacuum, then both the feather and the bowling ball will be pulling on the Earth simultaneously. The Earth’s acceleration would be the same towards both the bowling ball and the feather, because we would consider both the force of the feather on the Earth and the force of the bowling ball on the Earth when calculating the acceleration of the Earth.
2. You present this notion that two different systems can accelerate at 9.81 m/s/s towards Earth according to an observer standing on the surface of Earth; but when you place an observer on either surface of the two systems, Earth is accelerating at a different rate. This is classically impossible. If two systems are accelerating at 9.81 m/s/s towards Earth, then Earth must be accelerating 9.81 m/s/s towards both systems too.

You realize that you’re currently being con’d. Netanyahu wants Trump to win the presidential election, because he knows Trump will be friendly towards his genocidal actions. Netanyahu is doing everything in his power to extend this genocide so that he can stay in power; and so that he can keep single issue voters like you away from the polls.

Netanyahu knows that if he ended Israel’s genocide before the election, the Biden administration would receive credit in playing a role in mediating the conflict. This would likely assure a Harris victory. By escalating the conflct, he is assisting Trump. Why would you think that this genocidal maniac is doing this?

So here you are, the single issue voter that is tuning out all of the other important issues. For example, Trump considers communist (all you genius tankies) some of the biggest enemies in the USA; or how Trump backers and policymakers wants to remove women’s right to make decisions about their bodies.

Do I believe that Biden/Harris has done enough to help Palestinians? The answer is no. Do I believe Biden/Harris feels like Netanyahu and the Israeli government are in the wrong? Yes. Do I believe Trump feels like Israel is in the wrong? No.

So even if this is your single issue, as an American living thousands of miles from Israel, your best way to assist Palestinians right now is to put someone in the Whitehouse who at least views them as human-beings. By not voting or voting third-party, you’re not helping anyone but yourself. You are doing it so you don’t need to “feel bad” about crossing some morale boundary.

Listen man, if that’s the route you want to go, then fine. But I’m gonna go ahead and waltz my sorry butt to the polls and cast my vote for the person who will more likely do something to assist Palestinians even if I feel like I’m crossing a moral boundary. Am I gonna feel good doing it? No. But it’s the better decision to make, especially considering all the other important issues that surround this election beyond the Palestinian genocide.

Wasn’t it dragon age 2 where the level design got super repetitive though? It felt like they kept reusing the same exact level design in ways that didn’t really make sense.

By this metric, one can argue that we currently “misuse” a lot of words in the English language, but the reality is language evolves. Think about how the definition of “nice” has evolved from meaning “ignorant or stupid” in the 1300s to it’s current meaning.

FSR exists, and FSR 3 actually looks very good when compared with DLSS. These arguments about raytracing and DLSS are getting weaker and weaker.

There are still strong arguments for nvidia GPUs in the prosumer market due to the usage of its CUDA cores with some software suites, but for gaming, Nvidia is just overcharging because they still hold the mindshare.
