There must be a magnet in the train and in the track. ]]> 2021-08-23 20:37:55 UTC https://padlet.com/bgamsey/zkwjps4nos70j48b/wish/1691974726 Student Explanation 3 bgamsey https://padlet.com/bgamsey/zkwjps4nos70j48b/wish/1691975773  The train falls because of the force of gravity. Gravity acts between the train and Earth. Gravity attracts the train to Earth. ]]> 2021-08-23 20:38:52 UTC https://padlet.com/bgamsey/zkwjps4nos70j48b/wish/1691975773 Student Explanation 4 bgamsey https://padlet.com/bgamsey/zkwjps4nos70j48b/wish/1691976792  The train floats because there are balanced forces acting on it. There is a repelling magnetic force between the track and the train. There is an attracting force of gravity between the train and Earth. These two forces are the same strength and opposite directions so they are balanced. (There are also balanced forces when the train is resting on the track: gravity pulls the train down and a touching force from the track pushes it up.) ]]> 2021-08-23 20:39:54 UTC https://padlet.com/bgamsey/zkwjps4nos70j48b/wish/1691976792 Student Explanation 5 bgamsey https://padlet.com/bgamsey/zkwjps4nos70j48b/wish/1691977788  The train stops floating and falls back down because the magnetic force between the track and the train stops. It can stop because the magnet is an electromagnet and gets turned off. This makes the forces unbalanced. ]]> 2021-08-23 20:40:53 UTC https://padlet.com/bgamsey/zkwjps4nos70j48b/wish/1691977788 NGSS STANDARDS bgamsey https://padlet.com/bgamsey/zkwjps4nos70j48b/wish/1691997317 2021-08-23 20:55:58 UTC https://padlet.com/bgamsey/zkwjps4nos70j48b/wish/1691997317 Standards Met 1 bgamsey https://padlet.com/bgamsey/zkwjps4nos70j48b/wish/1691998390 DCIs:
