Since escape velocity depends on the mass of the planet or moon that a spacecraft is blasting off of, a spacecraft leaving the moon's surface could go slower than one blasting off of the Earth, because the moon has less gravity than the Earth.

Join us! What is launch velocity. Answers. A projectile is launched with an initial horizontal velocityfrom an elevated position and follows a parabolic path to the ground. Predictable unknowns include the initial speed of the projectile, the initial height of the projectile, the time of flight, and the horizontal distance of the projectile. Hope this helps.

Trajectory: While the theoretical maximum velocity is dictated by the rocket equation, a number of factors can sap energy during a rocket ascent. The magnitude of this energy leakage is controlled by the trajectory the rocket follows to get to its destination.

A few factors affect rocket launch and escape velocity, but they are different since the rocket is at different phases of flight at both times: By launch velocity I assume you mean the velocity with which the rocket leaves the launch pad. Here are the factors that determine that:

Escape velocity is the speed required for a rocket (carrying a satellite or some other type of payload) to theoretically escape the gravitational pull of an object such as a planet or a moon, assuming it does not produce its own thrust.

Launch a rocket from a spinning planet. 1  This movie shows the Deep Space 1 launch. 2  Earth goes around the sun at a brisk 107,000 kilometers per hour (66,000 miles per hour)! If our interplanetary spacecraft is aimed in the same direction Earth is already going, it will get a big head start.

The best times to launch the rocket are called launch windows.. As a glass window is an opening in a wall, a launch window is an opening in time. Usually, engineers will try for the beginning of the first launch window. However, several things can delay a launch.

If a projectile has a time of flight of 8 seconds and a horizontal velocity of 20 m/s, then the horizontal displacement is 160 meters (20 m/s • 8 s). If a projectile has a time of flight of 8 seconds and a horizontal velocity of 34 m/s, then the projectile has a horizontal displacement of 272 meters (34 m/s • 8 s). The horizontal displacement is dependent upon the only horizontal parameter that exists for projectiles - the horizontal velocity (vix).

This the principle with which rockets are launched. Scientists calculate what is the optimum height to keep the satellite in the orbit considering many constraints. Now regarding the escape velocity, it is the minimum velocity with which an object has to be thrown so that it escapes the clutches of Earth's gravity.
