Rocket Power : Rocket Power Finding Velocity and Acceleration at the speed of rockets What is a Rocket? : What is a Rocket? A rocket is a vehicle which has the capability to carry a payload (amount of weight) into space.
Model rockets are a scaled down version of real rockets that power into space
To make a rocket at home from a 2 liter bottle check out http://adc.gsfc.nasa.gov/adc/education/space_ex/2liter.html Rocket Motors vs Rocket Engines : Rocket Motors vs Rocket Engines Both devices create the thrust (force) to lift the rocket off the ground (into space).
Motors – A simple device used to convert stored propellant (fuel) into hot gases to produce thrust (solid propellants).
Engines – A complicated machine with moving parts to convert stored propellant (fuel) into hot gases to produce thrust (Liquid propellants). Types of Rockets : Types of Rockets Solid Fuel Rockets
These rockets use a dry mixed propellant
Mixture of fuel and oxidizer
Most common in model rockets
Liquid Fuel Rockets
These rockets use a liquid propellant stored in separate containers
Oxidizer Personalities of Rocketry : Personalities of Rocketry Chinese – Discovered a simple form of rockets made out of bamboo. They then used them to fire arrows at their enemies
Mongols – The enemy of the Chinese and responsible for spreading rocketry to the Western (European) world
Johann Schmidlap – designed the first multistage rockets to power higher fireworks into the sky
Kronstantin Tsiolkovsky – Father of Modern Astronomics; had the first idea to use liquid propellants Formulas to know : Formulas to know Velocity
V=Velocity, D=Distance traveled, & T=Time
A=Acceleration, F=Force (Thrust), & M=Mass Questions to answer about rockets? : Questions to answer about rockets? What is thrust?
