The Space module of Year 12 Physics covers the way that objects move in space. To this end, it covers weight force and projectile motion to explain how to launch artificial satellites and astronauts safely. It continues with the study of the solar system and gravity, revealing how planets orbit the Sun, and the Sun orbits the galactic centre. Finally, it moves on to Albert Einstein's theory of special relativity, and the unusual effects that occur when objects travel at speeds close to the speed of light. The physics covered in this module are very important for both the short-term and the long-term future of space flight.
