    Hi,
    I was doing some questions and i made an observation ( i'm not sure if it is correct).
    is it true that the centre of gravity in any object is where the weight acts vertically downwards? (i.e where most of the weight is found?)
    Any assistance will be kindly appreciated. thanks!

    no idea this is what I do know about theroies of gravity that might be able to help but it has to do more with light though actually; imagine a tapastry that is a tiny bit elastic pulled out so that there is no slack if you roll a ball on the tapestry then it would go from one side to the other no problem put if you put a ball(ball 1) on it and then roll the other ball on the tapestry again it will curve because of how the ball 1 is resting that explains the bending of light exactly when a golfer just misses the put and the ball starts going straght in another direction.


    P.S. if the you are talking about an object made out of one substance as long as you take out chunks of it with the same volume they would have the same wieght.

    there is a centere of gravity but that has to do with balance where you can balance something on your finger kind of deal and it can be affected by alot of things.

    Yes, by definition, The gravity vector acts through the centre of gravity, ie. if the CoG of an object is not supported, gravity will tend to rotate the object around its support, and, it will fall over.
