1. SCIENCE of MAGLEV Scientific Concepts Seen in Maglev Vehicles

2. Properties of Maglev Vehicles Energy- efficient Extremely Fast Advantages of Maglev Vehicles!

3. Science of Maglev There is no doubt that principles of science have been tried and tested in the development of maglev vehicles. What were your findings? What 3 scientific concepts do we see working in magnetic levitation vehicles?

4. 3 Scientific Concepts The three main scientific concepts seen in maglev vehicles are: Magnetic FieldsFrictionAerodynamics

5. Magnets Define magnetic fields. Magnetic fields – A region around a magnetic material or a moving electric charge within which a force of magnetism acts.

6. Magnets How do magnets work? Magnets have two poles which either attract or repel. RULE 1: Opposite poles attract RULE 2: Same poles repel

7. Magnets RULE 1: Opposite poles attract RULE 2: Same poles repel In a maglev train, the properties of magnets cause two forces. Repel=LIFT Attracting=THRUST

8. Properties of Maglev Vehicles ENERGY- EFFICIENT Extremely Fast Advantages of Maglev Vehicles!

9. Friction Define friction. Friction – The resistance that one surface or object encounters when moving over another.

10. Friction Think about this: Is friction involved with maglev vehicles? ◦NO!

11. Properties of Maglev Vehicles Energy- efficient EXTREMELY FAST Advantages of Maglev Vehicles!

12. Aerodynamics Define aerodynamics. Aerodynamics – The study of the properties of moving air, especially the interaction of the air and the solid bodies moving through it. Think of a sports car…

13. Aerodynamics Think about this: Are maglev trains designed to be aerodynamic? ◦YES! What makes them aerodynamic? ◦Their shape!

14. Properties of Maglev Vehicles ENERGY- EFFICIENT EXTREMELY FAST Advantages of Maglev Vehicles!

15. the BIG IDEA Science: Magnets, friction, aerodynamics Allow for: Energy- efficiency and extremely fast speed Ultimately lead to: Advantages of Maglev Transportation

16. YOUR TURN!!! Now you are going to apply your knowledge to watch these scientific principles at work! In your groups, you will take turns travelling to 3 stations: ◦Magnetic fields ◦Friction ◦Aerodynamics You will complete an activity at each station!
