Can you use kinetic energy of punches?

[RemainsAE]

Are you able to calc the kinetic energy of a punch?

Let's say a character punches at over light speed and we know their official weight is 180lbs, if you calc the weight of the arm and speed of the punch (0.99c), can that kinetic energy feat be accepted?

I'm just wondering since i've never really seen anyone calc like this.

FTL KE is a no-no.

Anything below FTL... is case-by-case for human sized people, but giant-sized objects at least taller than 5 meters easily qualify for KE IIRC. But speeds that high usually require further evidence.

But IRL situations, yes, you can use KE for those cases.

but doesnt humans also have KE?

if it's in the form of a full-power tackle or there are statements for KE working like that, yeah. Hence, case-by-case basis.

yeah I know you can't calc at ftl

Basically

FTL KE: no

Human-sized KE: Case-by-case basis

Giant-sized KE: If there is a solid timeframe to go off of, go for it.
