Hi all. i have seen some videos on youtube and i am amazed by the videos of Gaussian accelerator/ Magnetic linear accelerator. As i have a physics project coming up i may consider using this for my project, however i need to ensure that this experiment is within my syllabus. i have basically seen explainations from comments by other people in youtube and i realised there are many different type of explainations from people. Some explainations are * Newton 2nd and 3rd law*, *Conservation of energy, conservation of momentum* and something related to the * Newton's cradle* Base on people explaination, i did check them up on Wikipedia but i can't really seem to understand or confirm my understanding. Thus i hope people here can provide assistance such as provide me with explaination for this experiment. If there is one, include the laws in explaination. Below are some Videos that i have watched related to Gaussian accelerator/ Magnetic linear accelerator. （Not mine) http://www.youtube.com/watch?v=i6JCzkSAc5E&feature=related http://www.youtube.com/watch?v=epf1AUvG32M&feature=related All helps are appreciated!
