2. A simulation can also be a pretend version of something, like a fire drill or a flight simulator. [tree →](https://mova.elamur.ai/free/en/corpora/dictionaries/school/S/simulation/#m2)
3. (formal) Simulation can mean pretending, putting on a false show: a simulation of interest. [tree →](https://mova.elamur.ai/free/en/corpora/dictionaries/school/S/simulation/#m3)

### In the lessons

In science and computing lessons, pupils use simulations to see things that are too big, small, fast, slow or dangerous to test for real: planets moving, volcanoes, the spread of germs, circuits. Pilots train in flight simulators. In maths, a simulation can repeat a random event (like rolling a dice many times on a computer) to estimate a probability. Games like city builders are simulations too. Phrases: «computer simulation», «flight simulator», «run a simulation».

### Examples

### Note

Verb: «simulate», adjective: «simulated». A simulation is only as good as its rules: it can be wrong if the model is wrong. Not the same as «stimulation» (exciting or waking something up).
