The nomological-deductive model of scientific explanation

- you explain a phenomenon or an event of any kind by showing that it is an instance of a universal law known to be true.

Example - dropping a shoe on the floor. 

How would you get a scientific explanation of an event like that?

You refer to Newton's universal law of gravitation. All objects attract each other with a force directly proportional to the product of their masses and inversely proportional to the square of the distance between them.
 
The right answer to the question Why did the shoe fall toward the center of the Earth? is not Things like shoes always fell when I dropped them in the past - that's a generalization based on past experience. The right answer therefore is It had to.
(Ph.D. Daniel Robinson)
