How to move an ungrouped object?

hi guys,
i pressed “P” to ungroup an object from another object successfully but i couldn’t just move this ungrouped object solely but moved both objects. how to solve it? I just want to move the ungrouped object only not both objects.
Many thanks in advance!

do you mean - alt “P” - to clear parent?
if they are not grouped anymore, they should not move together anymore.
If now you want them to still be grouped and animate the children by itself, you can use some constraint.


Thanks for your reply!
I meant i just press “P” in edit mode and then chose “selection” to ungroup it. Today i just redo this action and don’t know why i can animate the children successfully.
Thanks Anyway!
