Will lenses that work on a D3000 fit a D7000?

I have a nikon D3000 and have two lenses for it, one is a AF-S DX NIKKOR ED 55-200mm 1:4-5.6G

and the other is a 18-55mm 1:3.5-5.6G VR

i'm now looking to buy a D7000 and was wondering if these lenses would also work on the D7000

Yes your lenses from your D3000 will work perfectly on your new D7000. One nice thing about the D7000 is that you can now save money by buying Nikon AF lenses instead of the more expensive AF-S versions because the D7000 has a focusing motor in the camera body.

Here is a nice video tutorial on the D7000:
