Most rockets need to be supported and held down for a few seconds after ignition while the engines build up to full thrust. The vehicle is commonly held on the pad by hold-down arms or explosive bolts, which are triggered when the vehicle is stable and ready to fly, at which point all umbilical connections with the pad are released.

A gravity turn is commonly used with rocket powered vehicles that launch vertically, like the Space Shuttle. The rocket begins by flying straight up, gaining both vertical speed and altitude. During this portion of the launch, gravity acts directly against the thrust of the rocket, lowering its vertical acceleration.
Musk’s sports car managed to sneak back up on the professionals charged with tracking objects in our solar system for several reasons. One key factor: Experts haven’t been all that interested ...
The account of the JATO Rocket Car was one of the original Darwin Awards winners: a man who supposedly met his death in a spectacular manner after mounting a JATO unit (a rocket engine used to help heavy aircraft to take off) onto an ordinary automobile. It was originally circulated as a forwarded email. [1]
A Soyuz-FG rocket launches from "Gagarin's Start" (Site 1/5), Baikonur Cosmodrome. A rocket (from Italian: rocchetto, lit. ''bobbin/spool'', and so named for its shape) [nb 1] [1] is a vehicle that uses jet propulsion to accelerate without using any surrounding air. A rocket engine produces thrust by reaction to exhaust expelled at high speed. [2]
A rocket's required mass ratio as a function of effective exhaust velocity ratio. The classical rocket equation, or ideal rocket equation is a mathematical equation that describes the motion of vehicles that follow the basic principle of a rocket: a device that can apply acceleration to itself using thrust by expelling part of its mass with high velocity and can thereby move due to the ...
The world’s first 3D-printed rocket made it off the launch pad Wednesday night but failed to reach orbit in a key test flight by a California-based aerospace startup.
The rocket caught fire, just before launch, and the LES carried the crew capsule clear, seconds before the rocket exploded. The crew were subjected to an acceleration of 14 to 17 g (140 to 170 m/s 2) for five seconds and were badly bruised. Reportedly, the capsule reached an altitude of 2,000 meters (6,600 ft) and landed 4 kilometers (2.5 mi ...
