How real rockets work



Real rockets work just the same as the model bottle rockets that we made for arts fest. Rocket engines instead of using water expel gases and the pressure that is used to expel these gases come from the burning of fuel.When the fuel is burn, the energy released increases the temperature of the gases that created when this fuel is spent. These super heated gases want to expand which causes the pressure to increase. As the pressure increases, the gases are pushed out the back end of the engine which because of Newton's third law of motion also push the rocket engine and everything attached to it in the opposite direction.
