The loss left Alan Pardew's side lying 16th in the Premier League standings, five points off the relegation zone with three games left to play.
Newcastle were demoted to the Championship in 2008-09, and Ameobi is hoping the club can learn from their past mistakes to avoid another season in the second tier.

"Nobody is too good to go down, as we found out last time. I'm sure the players understand that, and that's what the manager will be impressing on us this week.
"If someone comes to your home patch and does that to you, it is never a nice feeling. I have seen a lot of anger in that dressing room, which is understandable."
Newcastle have now won just three of their last 10 Premier League games and Ameobi has called for more courage from the rest of the squad in an attempt to eradicate the sloppy defensive errors that littered Saturday’s loss.
"On top of our last home game, that was very disappointing," the striker continued. "The manner of how we lost is the most disappointing thing.
"You start the game wanting to give everything you have, but to then go down two goals quickly to a good side like that, you are struggling.
"Once that third goal went in, it was game over. It's a fact we didn't tighten up as a group. We needed composure on the pitch, and we didn't have that."
