What are induced-dipole forces? How do they differ from dipole-dipole forces?

Induced dipole is where one molecule with a dipole causes one molecule without a dipole to have a temporary small dipole due to the repulsion of electrons. Dipole-Dipole is where two molecules with dipoles repel each other's electrons, which has a stronger effect.

These "induced-dipoles" are referring to the repulsions of the electrons in an element. They are instantaneous and all always happening . It is the weakest IMF but is involved with every element.

dipole-dipole forces are when two polar molecules become attracted to each other. An induced dipole is when something is not normally polar, but becomes polar for a small instance because of the attraction of another molecule with a dipole

Induced dipole is when there is a molecule that is not polar or has no dipole moment, but then it experiences a temporary dipole moment because of the dipole moment of another molecule. A dipole dipole moment is where there are two molecules that experience attraction between the partially positive charged end of one molecule and the partially negative end of the other molecule.

so would that make the D-D bond the stronger of the two?

Yes. Ion-ion > ion-dipole > dipole-dipole > LDF
