Answer: Newton
Explanation:-
Force is defined as an interaction that causes an affected object to be pushed or pulled in a certain direction.

where m= mass of an object
a = acceleration of the object
S.I unit of mass is kg and S.I units of acceleration is 
Thus For S,I units of force:

I don’t think so because an ice cube melting needs heat and relies on temp while ooblecks transition from solid to quickly depends on force and speed
