As a quick fix, since captions use SEQ fields for numbering, you
can manually edit the underlying field codes at the appropriate places
in your document to force a restart of numbering: Press ALT+F9 to
display field codes. You'll find that your captions look similar to
the following: { SEQ Figure \* ARABIC } and { SEQ Table \* ARABIC }.
Go to the first caption that should be renumbered, and add the \r 1
(where "1" is the number one) before the SEQ Figure and SEQ Table
parts, like this: { SEQ Figure \r 1 \* ARABIC } and { SEQ Table \r 1
\* ARABIC }, respectively. Repeat this procedure for each caption
which should be restarted.
When you are done, press ALT+F9 again to hide field codes. In order to
see the correct (updated) field results, select the entire document
and press F9.
Note that this approach will not add the chapter number to the
caption; if you must have these numbers, you'll have to type them in,
which is a time-consuming task, depending on the number of captions in
your document.
In the future, if you want to easily insert captions each of which
restarts on each chapter and includes the current heading number, you
need to learn about paragraph styles and make use of the built-in
headings, named "Heading 1" through "Heading 9". Also, you'll have to
add paragraph numbering to these headings.

For information about heading numbering, see:

When you are using one of the built-in heading styles for your
chapters titles, you can do the following: Choose
Insert>Reference>Caption (or Insert>Caption for Word 2000 or Word 97).
In the Caption dialog box, make sure "Figure" is the chosen "Label",
and then click the Numbering button. Click to check the "Include
chapter number" option and choose the appropriate built-in style to
restart numbering from, and then click OK. Repeat this procedure for
"Table". When you are done, click Close to close the Caption dialog
box.
