Realistic games

• In order for games to appear realistic the
  programmers have to use what's called a physics
  engine, a piece of software that uses physics to
  find out what happens next.
•  
• In 10-pin bowling the ball collides with some
  skittles, which may then collide with others
  (hopefully!). The speed of all the objects will
  change during this. What rules govern what speed
  they will move away with?

Task

• We can all describe roughly what will happen to
  the ball and a skittle but the game needs to
  respond very precisely to small changes in how
  fast it is hit or in what direction it is hit.
•  
• Your task today is to find the equations which
  govern the speed the objects will move away with
  after a collision. To keep it simple we will
  not include concepts like air resistance or spin
  and we'll deal only in one dimension.
•  
• We will then try to use these equations in a very
  simple simulation. In the first level we will
  assume the speed of the ball after the collision
  and calculate the speed of the skittle. In the
  second level you need to work out the speed of
  both.
