In most fish, the tail provides forward thrust. However, I have seen certain fish use their pectoral fins to provide sustained forward thrust.

Yes, of course orcas are more powerful than sharks. That is one reason why orcas are called killer whales. Orcas are bigger, faster, smarter and stronger than sharks. Sharks are amazing killing machines though, but they are easy meals for orcas to eat!

Many sharks' gills are shaped in a way so that they can obtain water only when moving forward. If the shark, for some reason, stops moving forward it will begin to suffocate. The suffocation can be cancelled when the shark starts moving forward again.
In the same way that all sharks move - by waving their tail from side to side, creating forward propulsion.
