Mass-spring oscillation is indeed possible in zero gravity, as demonstrated by a spring mass system on a frictionless horizontal plane. In this scenario, gravity is countered by the normal force, allowing the system to oscillate effectively. Introducing an initial velocity perpendicular to the spring results in two-dimensional oscillations, while free space facilitates three-dimensional oscillations. The principles of oscillation remain consistent regardless of the gravitational environment. Understanding these dynamics is crucial for applications in space physics and engineering.
