Roll may refer to:
== Physics and engineering == Rolling, a motion of two objects with respect to each-other such that the two stay in contact without sliding Roll angle (or roll rotation), one of the 3 angular degrees of freedom of any stiff body (for example a vehicle), describing motion about the longitudinal axis Roll (aviation), one of the aircraft principal axes of rotation of an aircraft (angle of tilt to the left or right measured from the longitudinal axis) Roll (ship motion), one of the ship motions' principal axes of rotation of a ship (angle of tilt to the port or starboard measured from the longitudinal axis) Rolling manoeuvre, a manoeuvre of any stiff body (for example a vehicle) around its roll axis: Roll, an aerobatic maneuver with an airplane, usually referring to an aileron roll, but sometimes instead a barrel roll, rudder roll or slow roll Kayak roll, a maneuver used to right a capsized kayak Roll program, an aerodynamic maneuver performed in a rocket launch Roll rate (or roll velocity), the angular speed at which an aircraft can change its roll attitude, typically expressed in degrees per second
