The minimum velocity required for an object to leave Earth’s gravity is called escape velocity. Write a detailed report and calculate the escape velocity for all the planets of our solar system and also for the Moon. What do the results imply?

Answer:
Explanation:
In physics (specifically, celestial mechanics), escape velocity is the minimum speed needed for a free, non-propelled object to escape from the gravitational influence of a massive body. It is slower the farther away from the body an object is, and slower for less massive bodies.
Escape velocity is only required to send a ballistic object on a trajectory that will allow the object to escape the gravity well of the mass M. A rocket moving out of a gravity well does not actually need to attain escape velocity to escape, but could achieve the same result (escape) at any speed with a suitable mode of propulsion and sufficient propellant to provide the accelerating force on the object to escape.
The escape velocity from Earth is about 11.186 km/s (6.951 mi/s; 40,270 km/h; 36,700 ft/s; 25,020 mph; 21,744 kn)[1]
