Weak: Yowai (弱い) vs Amai (甘い)


I'm an avid anime fan, and I have noticed that sometimes "Amai" (甘い) is
translated as "Weak!" (recently in Scarlet Nexus Episode 3, where a man says
it after dodging another fighter's attack, at 20:38 - [see
here](https://www26.gogoanimes.tv/scarlet-nexus-episode-3)) and "Yowai" (弱い)
has been used to mean "Weak" as well.

If "Amai" and "Yowai" can both mean weak, then what is the difference between
the two when using it to refer to weakness?




甘い can be used to describe something that lacks a required level of sharpness,
tightness, resilience, etc.

> ピントが甘い。  
>  (of a photo) It is a bit out of focus.

> ねじが甘い。  
>  The screw is a bit loose.

It could also be used to describe a ball that doesn’t have enough air
pressure.
