Removing apps and data from old ipad

Sorry in advance if this is a dumb question. I bought a new ipad this week and successfully created all from the backup of my old ipad. My question is, if I delete apps or data from my old ipad, will it also disappear from my new one (given it’s the same id)? I don’t need them to be in synch, just that the old 16 gb ipad needs some space.
