If I'm ×4 strong and my club is ×4 heavy, do I hit you with ×16 force?

This is more physics than GURPS, I suppose, but I want to know because of GURPS. It's more of a thought experiment, but it's because of GURPS that I have these thoughts, which means I should really blame the GM who introduced me to it in the first place.

You have ST 10 (BL 20) and a knobbed club that weighs 2 lb.

I have ST 20 (BL 80) and a knobbed club that weighs 8 lb.

I don't care about the damage yet, but I want to know if I'm hitting you with ×16 amount of force because I'm four times as strong and my club is four times as heavy. Of course, I'm sure physics is a bit trickier than just that, but do I have the right idea? If not, I'd love to be corrected. If I'm right, wouldn't giants kill each other too easily? At ST 20, I am assumed to have four times the mass, but I'm hitting with 16 times the force. Doesn't that mean me and my other ST 20 friend pose a greater threat to each other than you and your other ST 10 friend? Is this why larger creatures (bears, elephants, etc.) seem to have higher DR on top of their higher HP?

On the other end of the spectrum, what about those two ST 5 goblins in my backyard? They are ×1/4 as strong and their knobbed clubs are ×1/4 as heavy. So, it seems they are ×1/4 the mass but hitting each other with ×1/16 the force. Is it going to take them forever to knock each other out? Does that make sense? Do small creatures (ants, squirrels, etc.) have that same issue? (It seems like some ants have Striking ST on their mandibles, which might offset that a bit.)

Spoiler:  

GURPS does seem to support this. You and your friend are doing 1d+2 crushing damage (+1 from the knobbed club) to each other with your knobbed clubs; so, it'll take ~1.82 hits to knock the other to 0 HP. Me and my friend are doing 3d+4 crushing (+2 from the knobbed club, which was sized up using LTC2) with our knobbed clubs; so it'll take ~1.38 hits to knock the other to 0 HP. With punching, it'll take you and your ST 10 friend ~6.67 hits to knock the other to 0 HP, and it'll take me and my ST 20 friend ~3.33 hits to knock the other to 0 HP.

Likewise, for the ST 5 goblins, they are doing 1d-2.5 crushing (+0.5 from the knobbed club, which was sized down using LTC2) with their knobbed clubs; so, it'll take ~5 hits to knock each other to 0 HP. I won't touch punching because the damage numbers get too weird. But that illustrates the point.

Does that make sense? Again, it's more of a thought experiment than anything else. While the GURPS numbers don't line up with my assumptions (and I didn't expect them to), they do trend in those directions, which makes me feel like I can't be far off.

Thanks.
