A worksheet contains columns, rows and cells and is where you do your work. Each worksheet has a name. You can have more than one worksheet in a workbook.

Moving a chart from a worksheet will not affect that worksheet's name. So in this case, it would still be Sheet1. If you move a chart to another worksheet, embedding it there, that does not affect the name of that worksheet. So it could b embedded on Sheet2 or Sheet3 or whatever name may have been given to it.
