Newton's Laws of Motion: Click here for image **Newtons First Law** states that an object at rest or at motion will stay that way until an outside force acts upon it. **Newtons Second Law** states that Force equals Mass times Acceleration **Newtons Third Law** states every action has an equal and opposite reaction

Newtons third law! Jordan and I are playing tug of war with mrs. Dicks computer cord!

=__**TYPES OF ROCKETS:**__= **Model Rocket: **Materials used are cardboard, balsa-wood and plastic (NO METALS). Commercial motors up to type "G" are the only allowed motors in this category. They have a parachute or streamer on board to slow down the rocket during descent. **Micro Rocket:** These are small rockets are build out of light materials as cardboard and balsa-wood. They use commercial motors and don't use a electronic ejection system for the parachute. They usually attain an altitude of 25 to 200 meters and can therefore be launched from relatively small areas. **High Power Rocket: ** High Power Rockets are much bigger and more materials are allowed to be used. They can have flight electronics on board for measurements, flight control and tracking, in flight video capturing. They always use commercial motors. These rockets can achieve heights of several kilometers. **Mini Rocket: **These rockets are a first introduction to experimental rockets. The main objective is to get the rocket safe back to the ground with a parachute released by an electronic system. Because of their size they have to be launched from a launch tower and on military ranges. <span style="font-family: 'Times New Roman','serif'; font-size: 93%; line-height: normal; margin: 0in 0in 10pt;">They may contain some metallic parts, weigh about 1 to 2 kg and reach altitudes below 100 meters. **<span style="color: black; font-family: 'Times New Roman','serif'; line-height: 115%;">Amateur (Experimental) rocket: **<span style="color: black; font-family: 'Times New Roman','serif'; line-height: 115%;">These rockets contain metal parts and electronics and can reach altitudes of a many kilometers.

__ Forces on a Rocket __ <span style="font-family: Calibri; font-size: 12pt; line-height: 115%; margin: 12pt 0in 0pt; text-indent: 0.5in;">There are four forces on a rocket. They are Lift, Drag, Weight and Thrust. The amount of weight depends on what parts are used in the rocket, the heavier the parts the heavier the rocket. The heavier the rocket the slower it will go. The thrust is how much energy the rocket releases to propel it into and through the air. It depends on how much pressure there is and what you use to make the rocket fly. Lift is what is used stabilize the rocket while in flight. Lift is used to overcome weight and balance the scale of weight ratio to the thrust power. Drag is the forces that go against the rocket and potentially slow the rocket down. As the rocket gets higher in the sky the forces going against the rocket are greater.

<span style="font-family: Georgia,serif;">[]

__ Rocket Parts __ There are 4 systems on a rocket. They are: -__structural system__ The structural system, or frame, is similar to the fuselage, which is where the cargo or passengers are in an airplane. The frame is built with very strong but light weight materials, such as titanium or aluminum, and usually employs long "stringers" which run from the top to the bottom which are connected to "hoops" which run around the circumference. The "skin" is then attached to the stringers and hoops to form the basic shape of the rocket. The skin might be coated with a thermal protection system to keep out the heat which is created by the air friction during flight and to keep in the cold temperatures needed for certain fuels and oxidizers. Fins are attached to some rockets at the bottom of the frame to provide stability during the flight. -__payload system__ <span style="font-family: 'Arial','sans-serif'; font-size: 10pt; line-height: normal; margin: 0in 0in 10pt;">The earliest payloads on rockets were fireworks for celebrating holidays. T. Following World War II, many countries developed guided ballistic __ - __ missiles armed with nuclear warheads for payloads. The same rockets were modified to launch satellites with a wide range of missions; communications, weather monitoring, spying, planetary exploration, and observatories, like the Hubble Space Telescope. Special rockets were developed to launch people into earth orbit and onto the surface of the Moon. -__guidance system__ <span style="font-family: 'Arial','sans-serif'; font-size: 10pt;">The guidance system of a rocket includes very sophisticated sensors, on-board computers, radars, and communication equipment to control the rocket in flight. Many different methods have been developed to control rockets in flight. The V2 guidance system included small vanes in the exhaust of the nozzle to deflect the thrust from the engine. Modern rockets usually rotate the nozzle to control the rocket. The guidance system also provides some level of stability so that the rocket does not tumble in flight. -__propulsion system__ <span style="font-family: Calibri; height: 154.75pt; margin-left: 144.25pt; margin-top: 77.95pt; position: absolute; visibility: visible; width: 206pt; z-index: 251657728;"> Most of a rocket is made up of the propulsion system. There are two main classes of propulsion systems, liquid rocket engines and solid rocket engines. The V2 used a liquid rocket engine consisting of fuel and oxidizer (propellant) tanks, pumps, a combustion chamber with nozzle, and the associated plumbing. The Space Shuttle, Delta II, and Titan III all use solid rocket strap-ons.
