What is the difference between 묵직하다 and 무겁다 if both mean "heavy" in terms of weight?

Question

Answer

무겁다 means "heavy"
묵직하다 means "heavier-than-expected"

Answer

Hello. :)

I'm a native Korean.
1. 묵직하다.
When I lift something which is not shown (for example, it's placed in the bag), I guess something in the bag is heavy. In this case, I say '묵직하다.'
2. 무겁다.
Regardless something is shown or not, if I feel it heavy, I say '무겁다'. '무겁다' is more generally used than '묵직하다'.

Hope it helps :)
