Why does an object with a heavy mass on one side not spin as much in air?

I am doing a physics project and I need to explain why it was smart for me to make one side of my object heavier than the other in order to stop it from rotating as much in air. (Please use physics principles or ideas that would help me to explain) Thanks!Why does an object with a heavy mass on one side not spin as much in air?
Gravity always acts at the center of mass. If the center of mass is not located at the center of rotation, then the force due to gravity will impart a torque on the rotating part which will eventually serve to impede the rotation of the object while it's in the air.
