@Said Abdulsalam I think the answer to your question is this. you should move the one object with the same vareable as the the other.

eg:

 //rot for object 1
 int rotY =0;
 
 
 void draw (){
  // object 1
  rectMode(center);
  popmatrix();
  rotate(rotY);
  rect(X,Y,20,20);
  pushMatrix();
  // object moving relative to object 1
  rect(rotY,500,20,20);
  rotY++;
 }

this will rotate rect 1 and move rect2.
