Final answer:
A gimbal is a piece of equipment that is mounted to a tripod and can move 360 degrees horizontally. It allows smooth rotation of the mounted device in any direction without affecting its stability or levelness.
Step-by-step explanation:
A piece of equipment that is mounted to a tripod and can move 360 degrees horizontally is a Gimbal. Unlike a camera, which is mounted on a tripod for stability, or a telescope that requires a motorized drive to track objects in the sky, a gimbal is designed to allow smooth rotation of the mounted device in any direction without affecting its stability or levelness. Gimbals are commonly used in photography and videography to achieve steady and fluid movements while capturing footage.
