PENDULUM EFFECT

Hello I am new to unity 3D, with a bit experience in programming. I was planning to create a project that includes creating a swinging pendulum bob. After reading some books, and messing around with unity, I am capable to create a ball, move the ball with mouse and also using keyboard keys, I know how to add the physics properties to the ball. The challenge which I am currently facing is on how to create a rope object, and to stick the rope to the ball so that the ball will hang on the rope. As for the pendulum bob effect, I assume that the physics effects will take care of that.
