The paper studies the influence of angular velocity on the electromagnetic force for one rotational charged object. In the complex octonion space, the radius vector and the integrating function of field potential can be combined together to become one compounding radius vector. The latter may be considered as the ‘radius vector’ in the complex-octonion compounding space (one function space). The complex-octonion compounding space will be regarded as the extension of one complex-octonion compounding field. In the complex-octonion compounding field, the angular velocity will impact the compounding field strength, field source and linear momentum and so on. The study reveals that the angular velocity has a direct influence on the compounding angular momentum, compounding torque, and compounding force and so forth, including the compounding force term exerting on the rotational charged object.
