What do this and $(this) mean inside a widget method like create?

For example, Having a widget like this,

$.widget("sample.CustomWidget", {
options:{
},
_create: function(){
// Here what do this and $(this) mean
}
});

Thanks in advance,

I have a jquery widget like this:

$.widget("ui.MyWidget", {
              options: {            
            Value1: 10,
            Value1: 20,
        },
// and other methods like _create,...
});

And, i am extending it like this:

$.widget("ui.MyExtWidget", $.extend({

        options: {            

            Value3: 30,

        }}, $.ui.MyWidget.prototype, {
        myNewMethod: function(){
            alert(this.options.Value1+this.options.Value3);
        }
}

I have to call the "myNewMethod" in my html.

My html code is like this:

$("#Div1").MyExtWidget();
$("#Div1").MyExtWidget("myNewMethod");

I am getting exception like this while using the above code cannot call methods on TimeSpanHeader prior to initialization; attempted to call method 'myNewMethod'

What is the way to call the "myNewMethod" method?
