Page for researching rockets. =__** Notes: **__ =
 * 1) [|] []
 * A rocket is a spacecraft,missile,and aircraft. Also for fireworks, and weaponary.
 * Rockets work by action and reaction
 * This means that energy pushes the rocket forward by throwing the rockets exhaust backward.
 * The first time rockets were used in the 13th century for the miliatary
 * In the 20th century rockets were used for interplantery and industries that was when we were in the space age
 * The first type of rocket is a chemical rocket and they are very common because there exhaust are rocket propellant
 * These rockets store lots of energy but when realised early KABOOOOM!!!
 * This can restricted with lots of testing and careful design
 * Many problems came up on space exploration like heat mangement, difficulty of re-entry, radition, and restroom facilities
 * 1) __**﻿How rocket engines work**__
 * Rockets engines allow ships to blast off into space with action and reaction
 * Only three countries have put people into orbit
 * Rockets use reaction engines, This is used from the Newtonian princpial which states" to every action there is and equal and opposite
 * Rockets have a lot of "kick" when they blast off aso like an shot gun or a fire hose
 * Also some rockets use jet propulsion
 * <span style="color: #0000ff; font-family: 'Comic Sans MS',cursive;">Some rockets are chemically with combustion engines
 * <span style="color: #0000ff; font-family: 'Comic Sans MS',cursive;">Some use exhaust gas that emit hot gases
 * <span style="color: #0000ff; font-family: 'Comic Sans MS',cursive;">Their are some rockets that use propellants like steam, solar thermal, and nuclear thermal.
 * <span style="color: #0000ff; font-family: 'Comic Sans MS',cursive;">Rocket propellant is mass is mass stored in a tank

<span style="color: #0000ff; font-family: 'Comic Sans MS',cursive;">__** Physic of rocket **__

> and ve= ehaust velocity
 * <span style="color: #0000ff; font-family: 'Comic Sans MS',cursive;">The the engines combustion chambers and nozzle work on high pressure to increase speed drasticly because of a fluid
 * <span style="color: #0000ff; font-family: 'Comic Sans MS',cursive;">If there is a opening in the chamber then exhaust so that is how exhaust comes at the end
 * <span style="color: #0000ff; font-family: 'Comic Sans MS',cursive;">As rocket mass decreases it becomes lighter and very fast and its speed changes
 * <span style="color: #0000ff; font-family: 'Comic Sans MS',cursive;">There are 4 parts to rocket that are affected
 * <span style="color: #0000ff; font-family: 'Comic Sans MS',cursive;">1st. Thurst - is the is the engine
 * <span style="color: #0000ff; font-family: 'Comic Sans MS',cursive;">2nd. Gravity -
 * <span style="color: #0000ff; font-family: 'Comic Sans MS',cursive;">3rd. Drag- is a force which pulls on oppostie of rocket motion this decreases the acceleration of the whitle sound
 * <span style="color: #0000ff; font-family: 'Comic Sans MS',cursive;">4th. Lift- is usually used on small rocket- powerd aircraft
 * <span style="color: #0000ff; font-family: 'Comic Sans MS',cursive;">A rocket can only have so much propllant and there is a formula Fn= mve
 * <span style="color: #0000ff; font-family: 'Comic Sans MS',cursive;">m= propllant
 * <span style="color: #0000ff; font-family: 'Comic Sans MS',cursive;">Impules is used to calucate rocket propellant burning

<span style="color: #0000ff; font-family: 'Comic Sans MS',cursive;">** __ Staging ﻿__ **

<span style="color: #0000ff; font-family: 'Comic Sans MS',cursive;">** __ENERGY__ **
 * <span style="color: #0000ff; font-family: 'Comic Sans MS',cursive;">Staging is a process where rockets break parts that are not needed to reduce mass
 * <span style="color: #0000ff; font-family: 'Comic Sans MS',cursive;">These are the parts that come off when staging they are tankage, structure, guidance, valces,and engines to decrease mass
 * <span style="color: #0000ff; font-family: 'Comic Sans MS',cursive;">Everybodyu knows that rockets makes lota iois noise but it dosent get there as soon as it lifts of WHY??????????????????????????????/
 * <span style="color: #0000ff; font-family: 'Comic Sans MS',cursive;">At lift has lots of ENERGY
 * <span style="color: #0000ff; font-family: 'Comic Sans MS',cursive;">Lot so fuel is lost on liftout because of air drag and and gravity drag all lost energy ends up in exhaust
