The parts of a rocket are the nosecone, the payload, the electronics, the body tube, the recovery system, the launch lug, the motor, and the fins.
**Information on rockets** **(Activity 2)** What is lift? LIft is a very complex concept. Lift all depends on air viscosity, body shape, and inclination. The equation for lift is L= CL p V(squared) divided by 2 times A. This equation is used by rocket scientists to determine the exact lift of the rocket.

What is Thrust? Thrust is the force that moves the rocket through air and space ( usually with engines). Thrust uses Newton's 3rd law which states tha t for every action there is an equal re-action. In this case, the working fluid ( fuel for the rocket) is applied to one side of the engine, and on the other side the thrust is equaling out the working fluid to cause power or thrust.

Interesting Facts=)!!! I discovered two interesting facts about a rocket and that is weight and drag. The weight of a rocket is the force generated by the gravitational attraction on the rocket.The aerodynamic forces, lift and drag, and the thrust force are. Drag depend on the density of the air, the velocity, the air's viscosity , and the shape and size of the body. The equation for Drag is D= Cd p times V(squared) divided by 2 times A.

 __ Four Forces of Flight __ · Weight- a gravitational force that acts on a rocket during flight that works to bring the rocket down · Thrust- generated by the propulsion system of the rocket that moves the rocket upward through air and space, and is explained through Newton’s 3rd Law -//For every action there is an equal and opposite reaction// · Aerodynamics forces- these forces act on the rocket as it goes through the air · Lift and drag- the force that allows the rocket to take off is the lift force and the drag force is usually much greater than the lift and tries to drag the rocket back down and in other directions.

__** Rocket Stability **__ Many things can cause the rocket to rotate around its center of gravity. From small gusts of wind, or thrust instabilities can cause the rocket to wobble, or change its direction in flight. If the center of gravity or those instabilities are in the way, then the rocket will rotate due to controversial nose and drag angles, and then the rocket will, well, not work .

There is a simple test that you can use on a rocket to determine the steadiness. Tie a string around the body at the location of the center of gravity. Be sure to have the parachute and the engine working and in. Then swing the rocket in a circle around you while holding the other end of the string. After a few circles, if the nose points in the direction of the rotation, the rocket is stable and the center of pressure is below the center of gravity. If the rocket wobbles, or the tail points in the direction of rotation, the rocket is unstable. You can increase the stability by lowering the center of pressure, increasing the fin area, raising the center of gravity, or adding weight to the nose.

To summarize, an object in rest/motion will STAY in rest/motion until a force is applied to it.

__ NEWTONS SECOND LAW OF MOTION __

Newton's second law of motion explains how an object will change velocity if it is pushed or pulled upon. Firstly, this law states that if you do place a force on an object, it will accelerate, i.e., change its velocity, and it will change its velocity in the direction of the force.

// ﻿ FORCE=MASS X ACCELERATION!!!!!!//

**Personal Additions**

Hi, My name is Kiri T. I am from Minden High School and I will be participating in the rocket extreme. I am 15 years old and I have never built a rocket but I am excited to make one. My team members consist of Zachary and Nicole H.!!!!!!

I love to eat but I'm not fat my friend nicole who sits besides me gets on my nerves but we still cool. Hopefully during this time she will get less annoying but she is really cool. I hope you meet this girl sometime soon but if you do come prepared.!!!!!!!!!:)

Hi, my name is Ashley. I'm from White Plains High School and I'm joining the rocket extreme. All of my group members are 15 years old and we've never built a rocket either. Everyone else is Ayan and Viki! *waves hi*!!

I like to draw, like my friend Viki, and we all love music! We can't live without it! I like to eat too, but not as much as Viki, who can eat 10 tacos and still be hungry(BUT SHES NOT FAT!!!) We all hope that we get along and have a bunch of fun! We may be a little nerdy, but we're still awesome!

Hi, im Zach. We need a team name!!! post your thoughts on the discussion board.

So far in my class we had to make a flag..............I made it because ZACH CANNOT DRAWWWWW hahaha...

DO WE HAVE ANY TEAM NAME IDEAS?
