Categories of High Speed Rails
High speed rails is a vague term that categorizes the trains based on their speeds, to be considered a high speed rail the train would need to be travelling at least 200 km/hr or greater in addition to passengers to be deemed as a high speed rail. These high speed rails may include conventional trains, trains that use tracks or unconventional trains, trains that does not touch the track (ex. maglev trains).
Introduction of Magnetic Levitation Trains
Magnetic levitation trains (maglev for short), operate through the use of a magnetic field that guides, propels and suspends the train above a guideway in which the train travels along. The maglev trains were conceptualized in the early 1900s by two Americans, Robert Goddard and Emile Bachelet, however the maglev train engine (linear motor) was first invented in 1905 by Alfred Zehden, a German engineer. The maglev trains are frictionless trains that are more efficient and they were invented for the purpose to reduce the impacts created from railroad trains.
How does magnetic levitation trains relate to Grade 11 Physics?
High speed rails specifically maglev trains, relates to three units in grade 11 physics. First off, high speed rails relate to kinematics because of the motion of the train as the train is able to cover an ample amount of distance in a short time frame, when compared to other methods of transportation. The maglev train is able to complete this action by accelerating and decelerating, which is found by using the train's final and initial velocity and this describes the motion of the train, thus relating to kinematics. Secondly, the maglev train relates to dynamics because of the magnetic field that propels the train forward however, factors that contribute to this forward force is the train's mass and acceleration, this forward force stimulates the motion of the train therefore relating to dynamics. Finally, maglev trains relate to electricity and magnetism as the train uses the basic principles of the forces of magnetism to guide, suspend and propel itself so it can function.
