How a rocket or rocket engine works to go from the surface of the Earth to Space. The example used is SpaceX's Falcon 9 both with their Dragon capsule to go to the International Space Station (ISS) and with Astrobotic Technology's Griffin lander and Red Rover rover to the moon. As well, a simple single stage rocket is used to explain some simple concepts.
Newton's 1st and 3rd laws, just two of Newton's three laws of motion, are explained along with how they work with gravity to allow rockets to fly and to orbit. What orbiting is is also explained. Solid fuel rockets, liquid fuel rockets and hybrid fuel rockets are also covered. And lastly, how multiple stages are used to get to space, SpaceX's 2 stage rocket with the Falcon 9 as the first stage being used as the example.
