1. The problem statement, all variables and given/known data I am trying to understand physics in terms of relationships rather than just equations, hoping this site would help me, thanks! So... You can expect lots of questions from me lol. Okay so right now it is momentum and acceleration. Trying to understand what could be a qualitative relationship between acceleration and momentum of an object 2. Relevant equations p=mv 3. The attempt at a solution I realize p[tex]\propto[/tex]mv therefore p[tex]\propto[/tex]m * at so since momentum is proportional to mass, acceleration and time, I am assuming when I have two momentum vectors - say, tail of vector p2 is attached to the head of vector p1-, acceleration vector of that object points in the same direction as the resultant vector of p1 and p2? By that order force is applied also in that direction? Thanks!
