Max Born's interpretation tells you where you can find a particle. I have a new interpretation that follows Born's: The particle spends less time where its momentum is high and more time where its momentum is low. The particle moves fastest where it is found the least and vice versa.
This quantum wave gives the particle a changing momentum. Some of the particles mass becomes greater motion where it is found the least often. As the particle decelerates its decreasing motion turns it back into its mass where it is found the most frequent.
