Is there a difference between Van der Waals and LDF?

Question stated above.

[Adrianh72]

LDF is a type of Van Der Waals.

[rabiasumar2E]

Van der Waals is usually used to describe all intermolecular forces. LDF is always included in it.

[Izzie Capra 2E]

Yes, the answers above are correct. And since LDFs are usually the weakest and temporarily attractive intermolecular forces, most molecules will experience LDFs.

[Jingyao Chen 4H]

Van der Waal Forces include dipole-dipole forces and LDF. In the lecture notes, however, Van der Waal is written as another name for LDF. I would recommend just use the name LDF when you are referring to the induced dipole moments between molecules.

I just wanted to add on that the book uses the term LDF and not Van der Waals, so I personally would stick with that.
