Basic game physics – from Newton to code

While we my not often think about it, movement of objects is one of the key aspects of most video games. In any game that has any sort of characters, enemies or items interacting in a fictional – or real – world, these agents and objects have to move in order for anything to happen.

In most cases, we want these movements to appear natural, or at least believable and consistent.

Ideally, their behaviour would also be reasonably complex and not entirely predictable, to make interacting with them more interesting.
