Gravitational waves are emitted in the space when a massive object undergoes a change in its motion.
Gravitational waves are emitted. Bends spacetime, ripples travel outward from a gravitational source at the speed of light. The more massive the object and greater its acceleration, the stronger the resulting gravitational wave.
Therefore, A change in motion produces gravitational waves.
Definition of Gravitational waves:
Gravitational waves are disturbances or ripples in the curvature of spacetime, generated by accelerated masses, that propagate as waves outward from their source at the speed of light.
