Question:
How does one describe the motion of whales as they move through water? Do they move similar to fish moving side to side?

Go to http://www.pbs.org/evolution

Click on the evolution library link. Select videos. Look for the videos that show the evolution of whales. One piece of evidence that whales evolved from land mammals is by the way they move when they swim. Their tail fins are vertical. Fish swim from side to side, whales' spines move up and down-their tail fins are horizontal.

Actually, they move directly the opposite of fish! Whales move their flukes (tails) up and down, propelling them forward.
