What is rocket science?
The thrust required for an object to overcome Earth’s gravity and atmospheric resistance and move towards space is called escape velocity. Besides Earth, the gravitational forces that can affect the object are those coming from the sun, moon and even other planets.
Apart from space vehicles and the military, rockets are used in life-saving rescue flares and fireworks, and even the ejector seats in military planes.
