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 putting the player has to take account of the
  slope of the green when playing their
  shot. What equation governs the effect of the
  slope?

Task

• We can all describe roughly what will happen to
  the ball on the slope 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 effect of the slope. To keep it simple
  we will not include concepts like friction or
  spin and will assume that the ball is struck at
  right angles to the slope.
•  
• 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.
