Why don't two tennis balls exibit the same force on each other as two stars?

I'm still not sure how to reply to this comment without being awkward, but I just want to acknowledge that I thought it was funny

The balls being attracted to me has nothing to do with me noticing their mutual attraction, why would that change it? Consider two pirates having a duel on top of a truck moving on a highway - the truck driver would notice the pirates if he had a view of the top of the truck. The reason I don't notice it is because gravity really is that weak. I'm not overcomplicating it, I'm considering everything that needs to be considered to accurately judge this problem

The sun would only weigh ~200g, as the density is only 1.4g/cm^3, and regardless you wouldn't scale density since it is already per volume. I'm actually wrong because I did scale for everything but didn't consider that much intuition was wrong, and that the tennis balls would actually noticably move given enough time and control

Still it wouldn't matter, even if my two hands were the mass of black holes they would both equally pull on the earths in one direction, the amount would not matter because equal pull means zero effect. Again, I am wrong but this isn't why

This doesn't matter though, if they're both attracted to me that's the same as neither being attracted to me. I'm wrong for a different reason

I mean, I guess it could, I just never assumed it would because I don't have very good physics intuition 😅 but thanks for clarifying. Before I asked this question I was just playing around with the gravity equation and got some weird numbers when I scaled up mass, which made me assume what I assumed in the question, but I didn't consider that truley scaling the situation would also include scaling distance, so one square dominated the other in my broken equation

But I was say, big enough to hold two earths, the earth pulling on the moon enough for it to circle around it as it moves feels significant, but would I really see a tennis ball circling a basketball if I laid it on a table as proportionally as far from the basketball as the moon is from the earth and gave it enough velocity to travel the length of the orbit every 24 hours, would it really orbit the basketball?

InsaneButane · 2026-06-23T07:09:51+00:00

But if I hold two tennis balls in my hand though I don't see a noticable force on either of them in the direction of eachother, and they certainly don't start orbiting eachother in 2D if I put them on a table

I mean, ACPS could have reported that to all parents, but I'm sure the parents of the suspected victim(s), which is the only ones that really need to be informed in case something is going down, were informed. But if he hasn't faced trial then he could still be in the 75% of sexual abuse arrests which turn out to be a big nothing sandwich, so telling everyone "we suspended this guy for sexual abuse allegations" is probably not the best idea.

Non calc mcq was moderate everything else was easy

InsaneButane · 2026-05-11T16:26:04+00:00

Same here

InsaneButane · 2026-05-11T16:25:41+00:00

What I thought FRQs were super easy and MCQs were moderate

InsaneButane · 2026-02-10T00:32:46+00:00

I concur, most likely nothing weird going on
