Chapter 6. Interacting objects: Newton’s Lab
topics: | objects interacting with each other, using helper classes, using classes from the Java library |
concepts: | collection, list, for-each loop, standard class library |
In this chapter, we shall investigate more sophisticated interactions between objects in a world. As a start, we shall investigate one of the most universal interactions between objects anywhere: Gravity.
In this scenario, we are dealing with celestial bodies (such as stars and planets). We shall simulate the motion of these bodies through space, using Newton’s law of universal gravitation. (We now know that Newton’s formulas are not quite accurate, and that Einstein’s theory of general relativity describes the motions of planets more precisely, ...
