Module 1: Rockets Pre Class Activity (do by your own) Q2. How do rockets work Class Notes How Rockets Work Rockets move using Newton’s Third Law : when hot gases are pushed down , the rocket moves up . This is called rocket propulsion . Fuel and oxidizer burn in the engine, making gases that shoot out at high speed. Types of fuels : Solid fuel → simple, powerful, can’t be stopped. Liquid fuel → controllable, used for big rockets. Cryogenic fuel (very cold liquid hydrogen + oxygen) → gives very high power. 👉 ISRO uses PSLV (workhorse), GSLV (for heavy satellites), and LVM-3 (heaviest rocket for moon and human missions). Theory Module 2: Rocket Transportation and Launch Pre-Class Analysis Questions (for discussion) How do you think such a huge rocket is moved from the factory to the launch site?
