Why can't we launch satellite by using electromagnet power?

One assumes that you are not counting the Earth's gravity as a "further acceleration". Then yes, a 11 km/sec velocity at the surface in any direction yields a trajectory that will escape to infinity, barring any other acceleration. Typically, that other acceleration will be present either by smacking head-on into the Earth's surface (if you aim downward) or air resistance (if you aim upward).Janosh89 said:Intuitively, if one ( or the vehicle ) could instantaneously achieve 11km s-1 at the surface , would it
of necessity escape the pull of the Earth's mass (gravity) if it did not undergo ANY further acceleration?
See https://www.physicsforums.com/threa...n-vehicle-escape-Earth's-gravity-well.954278/Similarly, if one had a hypothetical rocket that had an unlimited supply -internallyproduced- of thrust ,
then could that rocket continue into space / orbit without actually achieving the so-called ESCAPE VELOCITY?
Janosh89 said:As an addendum , do you always have to reach the standard escape velocity ?
Electromagnetic power is used to propel satellites into orbit by generating a magnetic field that interacts with the Earth's magnetic field. This interaction creates a force that propels the satellite forward, allowing it to achieve the necessary velocity to enter orbit.
Using electromagnet power to launch satellites has several benefits, including lower costs, greater control over the launch process, and reduced environmental impact compared to traditional rocket launches.
As with any technology, there are potential risks associated with launching satellites using electromagnet power. These include potential interference with other satellites and possible damage to the Earth's magnetic field. However, these risks are carefully studied and mitigated before any launch takes place.
The strength of the electromagnets used to launch satellites varies depending on the specific launch system. However, they are typically very powerful and can generate forces strong enough to propel the satellite into orbit.
No, satellites can only be launched using electromagnet power from specific locations on Earth, such as near the Earth's equator. This is because the Earth's magnetic field is strongest at the equator, making it easier to generate the necessary force to launch the satellite into orbit.
