The 20-year-old, younger brother of Shola, is on loan at Middlesbrough until the end of the season.
He told the Evening Chronicle: "I've already taken a lot from the games I've played, and I'm stronger physically.
"Hopefully, I can bring that back to Newcastle. Middlesbrough are trying to get in the play-offs, and I'm trying my best to help the club do that."
He admits that he is enjoying his spell in the Championship, but it is far from easy.
"It's not easy. The ball turns over a lot more. There's a lot more running," he said.
"You have to be strong, but I'm enjoying every minute of it. It's going well. I'm glad to be getting some games under my belt.
"I'm feeling part of the team. Hopefully, I'll continue getting games and impress the manager. Games are what I need for my confidence and development as a player.
"I'm playing week-in, week- out, and keeping my fitness levels on."
Ameobi is hopeful of helping Boro to the play-offs, despite their loss of form in recent weeks.
"Hopefully, we'll get that play-off spot. And Newcastle are doing great right now, especially in Europe."
