about physics SBA circular motion

physics 有個sba 係去study the relation between the angular velocity of the body in circular motion and the radius of its path.....

我想問應該有咩theory underlies the experiment???
同埋:
why the rotating string cannot be whirled exactly in a horizontal plane??
sources of error and the improvements for this experiment???

但應該點證明relation between the angular velocity of the body in circular motion and the radius of its path呢??
唔知背後用咩equation去prove...?
