yomama Posted June 15, 2009 Report Share Posted June 15, 2009 (edited) hey i m doing my EE in physics and I am sort of confused about the topic.my supervisor has advised something about "drag in liquids" but i m not too sure about it.can anyone suggest a better topic or this one is fine???

Mattias Posted June 15, 2009 Report Share Posted June 15, 2009 But what about drag in liquids?What kind of liquids?What kind of objects?This isn't nearly specific enough... Reply Link to post Share on other sites More sharing options...
yomama Posted June 15, 2009 Author Report Share Posted June 15, 2009 well its to do with different densities of liquids and also the mass and shapes of objects such as cubes and spheresthe research question can be narrowed down later but rifht now i am concerned whether i will be able to carry out experiments with this topic??

yomama Posted June 16, 2009 Author Report Share Posted June 16, 2009 i plan to analyse the velocity of the masses with different variables such as temp., drop height, viscosity (and density of liquids)i d be recording them using a high definition camera and also graph velocity and acceleration as a function of timedoes that make it a bit complex?????
