In the context of space, the velocity required for an object to start moving from a stationary position at the "zero point" depends on various factors.
Gravitational force: If the object is within the gravitational field of a massive celestial body, such as a planet or a star, the required velocity would depend on the escape velocity. The escape velocity is the minimum velocity an object needs to overcome the gravitational pull and escape the gravitational field. It is given by the equation:
v = sqrt(2 * G * M / r),
where: v is the escape velocity, G is the gravitational constant, M is the mass of the celestial body, and r is the distance between the object and the center of the celestial body.
The specific escape velocity varies depending on the mass and radius of the celestial body.
Orbital mechanics: If the object is already in orbit around a celestial body, the velocity required to start moving away from the "zero point" would depend on the orbital velocity. The orbital velocity is the velocity required for an object to maintain a stable orbit around a celestial body without falling back to the surface. It is determined by the gravitational force between the object and the celestial body. The specific orbital velocity depends on the mass and radius of the celestial body.
Thrust and propulsion: In space, if an object has access to a propulsion system, such as rocket engines, the velocity required to start moving from the "zero point" would depend on the thrust provided by the propulsion system. The object needs to generate sufficient thrust to overcome any external forces acting on it, such as gravity or atmospheric drag, if present.
In summary, the velocity required for an object to start moving in space from the "zero point" depends on factors such as the gravitational force, orbital mechanics, and the presence of a propulsion system. The specific velocity needed can vary depending on the specific circumstances and the properties of the celestial body involved.
