1. An unmanned aerial vehicle, comprising:
a plurality of motors configured to rotate a plurality of propellers;
a movable part configured to move a center-of-gravity position adjustment member; and
a control unit configured to control the movement of the center-of-gravity position adjustment member by the movable part, based on a difference between a first rotation speed of a first motor of the plurality of motors and a second rotation speed of a second motor of the plurality of motors, wherein
the movable part moves the center-of-gravity position adjustment member in a case where the difference is not a value within a predetermined range, and
the predetermined range is based on of an increase amount in weight of the unmanned aerial vehicle.
