Roll or bank is the aircrafts movement about its longitudinal axis. Since theyre located on opposing sides of the longitudinal axis, both ailerons need to move in the opposite directions to complement each others motion. This movement turns the aircraft about the longitudinal axis, making it enter a bank.

The principle is the same whether the aircraft gets thrust from propellers or jet engines. A propeller forces air backward, while a jet engine ignites a mixture of air and fuel to generate hot gases that eject backward. In jet engines, increasing throttle increases the fuel flow, producing more exhaust gases that can be flung backward.
