Under the influence of an initial force, each falling domino receives additional energy from external sources (such as gravity), converting it into kinetic energy to push the next one. This "perpetual motion" of dominoes takes place within an open system, relying on external stimuli and design rather than an infinite internal energy cycle.</span></p><p class="ql-block"><br></p>
