  1. How Rockets Work With a little history thrown in for fun

  2. Hero Engine ~100 BC

  3. Chinese Rockets - “Fire Arrows” in Military Use ~1200 AD

  4. First Manned Rocket?

  5. Isaac Newton • 1687 • Laws of Motion • Paved way for modern rocketry

  6. Robert Goddard First Liquid Fueled Rocket

  7. German Scientists Develop Long Range Missiles during World War II

  8. Newton’s Laws of Motion • In the absence of net external force, objects tend to maintain their state of motion • Acceleration is directly proportional to force applied and inversely proportional to mass • For every action force, there is an equal but opposite reaction force

  9. In the absence of net external force, objects tend to maintain their state of motion • If nothing pushes or pulls • Objects at rest, stay at rest • Objects in motion move in a straight line with constant speed

  10. Acceleration is directly proportional to force applied and inversely proportional to mass • If you push harder • The motion changes faster • If the object is heavier • You must push harder to get the same change in motion

  11. For every action force, there is an equal but opposite reaction force • Forces come in pairs • When an object can’t push back any harder, it moves away to lessen the push it is getting The rock pushes back He pushes the rock

  12. Applied to Rockets • The rocket will stay where it is until the engines ignite. The rocket will keep moving when the engines stop. • More mass requires bigger engines • Gasses are pushed backward by the rocket (action) the rocket is pushed forward by the gasses (reaction)
