If an object were to lose its gravitational pull, it would not lose its reference frame to the planet and sun, and would continue moving in a straight line unless acted upon by other forces. The concept of losing gravity raises questions about the fundamental laws of physics, which remain applicable regardless of hypothetical scenarios. Even if gravity were negated, other fundamental forces, such as electromagnetism, could still influence the object's behavior. In a practical sense, an object losing gravity would follow a trajectory determined by its initial velocity and the rotation of the Earth, potentially leading to it moving away from the planet. However, this scenario does not align with real-world physics, as gravity is a fundamental force that cannot simply be turned off. Sci-fi concepts like anti-gravity often explore these ideas, but they remain speculative and not grounded in current scientific understanding.
