Storyboard Text

  • You are absolutely right Dad and that is why I also have this. In this case the magnets are not touching but there is nothing in between them except air. Normally the force of gravity would prevent this from happening by pulling down on everything. However, since a forces exists between these two objects, even though they are not touching that allowed them to defy gravity and not touch. These objects can go without touching because of magnet repulsion, which is when two magnet with the same polarity are faced towards each other and repel each other. 
  • I'm disappointed in you Ella! I thought I taught you not to lie!
  • I'm not lying Dad! Forces can and do exist between objects, even when they are not in contact with each other! And I'm going to prove it to you! 
  • Now, lets see what I can show my dad to prove to him that I'm right! 
  • Do you know where we are Dad? We are at a Magnetic Levitation or MagLev Train Station! This things are crazy high tech! If you look close enough you can see that they are levitating! MagLev Trains prove that forces can be exerted on non-touching objects by using magnetic attraction and repulsion to lift a over 50 ton train off of the tracks. This means that the force(s) being exerted on these objects are very strong, strong enough to support 50 tons or more! This demonstrates forces being exerted on non-touching objects because if there was not a force being exerted the train would drop back down onto the tracks (due to gravity) and would not be able to move. 
  • Look Dad! Even though the magnet is not directly touching the iron filings the iron filings moved to the top edges of the magnet.  This happened because the North and South poles of the magnet were attracted to the iron filings. See how the filings clumped at the North and South poles of the magnet? This shows that forces can and do exist between objects that are not touching because if there were not any forces in between the magnet and the iron filings this reaction would not have happened; the filings would not have moved to the poles of the magnet.
  • Huh. Maybe you are right. But you need more than one piece of evidence to prove any claim. 
  • I guess your claim was right, but now I am pretty interested in this. Do you have any more examples? 
  • As  a matter of fact I do but I'm going to need you to drive us somewhere. 
  • So, where exactly are we going? 
  • You will find out soon enough! Just keep following my directions! 
  • Yup!
  • So, let me make sure I have this right because I think I might finally truly understand what you are saying. Forces can exist between non-touching objects and it is fairly common that they do. There are also many ways that they can be formed.
