| 释义 | impulse Symbol J. The product of a force F and the time t for which it acts. If the force is variable, the impulse is the integral of Fdt from t0 to t1. The impulse of a force acting for a given time interval is equal to the change in momentum produced over that interval, i.e. J = m(v1 - v0) , assuming that the mass (m) remains constant while the velocity changes from v0 to v1 |
