Oooh, I like cooking and I like science.
Caution geeking out ahead.
This is all for the crock pot.
You generally want a tougher cut of meat for pot roast. Tougher cuts if meat have more connective tissue (collagen) and when they cook at a low temp, around 225, they break down into gelatin and that creates a more tender roast with it's own gravy from the natural gelatin. 10 hours on low is my standard. If your short on time, 4-5 hrs on high will about right. The meat is more tender cooked on low.
I do use some liquid in my roasts and I make sure that at least one of my ingredients is an acid, like tomatoes, but using straight tomato juice as the only liquid makes it tougher. This explains why, if you're wondering. Marinades Add Flavor but Don't Always Tenderize - Fine Cooking Recipes, Techniques and Tips
Cooking liquids? I've tried it many ways. Beef broth with some worcestershire, red wine or tomato juice splashed in is good. So is the super easy onion soup mix packet with some water. I don't cover the roast with liquids, about halfway works great.
Browning (maillard reaction) does make it much yummier. Brown an extra minute or two on the second side, since the first side lowered the temp of the pan. Oh yeah, salt before browning.
Don't forget the onions and carrots.
Here's a awesome chart for different types of cuts of roast.
