Simulations can be used for many purposes. Here are some more examples :

| Games
| Many computer games attempt to mimic aspects of real life on a computer. For example :
| 1. | A football game may simulate the path that a football follows when kicked by taking account of how hard it was hit, where it was it, what part of the foot hit it, and how the wind is blowing.
| | 2. | A chess game can act as an opponent to a human by considering the impact on the game of the different moves it can make and taking the move that would give it the best overall advantage.

| Science Experiments
| Some science experiments are too dangerous or expensive to conduct. The way in which different chemicals or physical effects interact with each other can be modelled by a computer so that the results of an
experiment can be seen without having to carry it out.
|
| Weather Forecasting
| The weather that we experience is determined by many factors such as atmospheric pressure, temperature, wind direction, time of day and the relief of the land. Computers are used to produce weather
forecasts by simulating how these factors interact with each other and change over time. Powerful mainframe computers are required to carry out the complex calculations involved in
forecasting. Weather forecasts are not perfect because the model used to produce a forecast does not incorporate all of the factors that determine what will happen.

| Economic Modelling
| Organisations like the Treasury use mathematical models to simulate the effect that changes in economic variables such as the rate of interest, tax rates or exchange rates will have on the economy.
