Confused About Objects and Classes in CodeIgniter?

I am new to CodeIgniter and wonder. I am a little confused about classes, libraries and objects.

Does CodeIgniter replace the regular PHP method of user objects, i.e. $var = new car();, with libraries, that is $this->load->library('some_library'); $this->some_library->some_function();?

If both are valid, is there a difference? If so, what are the differences and when do I use one over the other? What is more common / correct?

I ask because I created the class, but I'm not sure if this is the correct way to create it.

Thanks in advance
