We study the gravitational wave (GW) production induced by the asymmetric jets of gamma-ray bursts (GRBs). The asymmetric jets result in a recoil force acted on the central compact object, whose motion leads to the emission of GWs. Under reasonable assumptions and simplifications, we derive the analytic form of the produced GWs. The amplitude of emitted GWs is estimated to be relatively low, but possibility exists that they can be detected by future experiments such as the Einstein Telescope. We find the dynamical properties of the central object, which is difficult to be studied via the electromagnetic channel, can be inferred by measuring the emitted GWs. Moreover, we find the emitted GWs can be used to determine whether the relativistic jets are launched by the neutrino annihilation process or the Blandford-Znajek process, which cannot be clearly distinguished by the current GRB observations. Our work manifests the importance of the GW channel in multimessenger astronomy. The physical information encoded in the GW and electromagnetic wave (EW) emissions of an astrophysical object is complementary to each other; in case some physics cannot be effectively investigated using the EW channel alone, including the GW channel can be very helpful.
