Self-balancing refers to the ability of a system or device to maintain its equilibrium without external assistance. This concept is commonly seen in technologies like self-balancing scooters and robotic systems, where sensors and algorithms work together to adjust the position and orientation of the device. By continuously monitoring its balance, these systems can make real-time adjustments to stay upright. In the context of physics, self-balancing can also apply to natural systems, such as ecosystems that regulate themselves to maintain stability. For example, predator-prey relationships help control population sizes, ensuring that no single species dominates the environment. This balance is crucial for the health and sustainability of the ecosystem.
