Define simulation.
A simulation is a program that models a real-world object, event, or phenomenon using simplified representations.
How do simulations use abstraction?
Simulations use abstraction to represent complex objects by focusing on relevant features and ignoring unnecessary details.
How does a simulation mimic real-world behavior?
A simulation mimics real-world behavior by tracking how the state of objects changes over time in response to conditions or inputs.
Name three applications of simulations.
Simulations are used for impractical event modeling, hypothesis refinement, and variability simulation.
True or False?
The results of a simulation are guarantees of what will happen in reality.
False.
Simulations are simplified models, so their results are approximations, not guarantees.
Why might events such as crash tests be simulated rather than tested physically?
Crash tests are simulated because they are too dangerous, expensive, or time-consuming to test in the real world.
How do simulations model unpredictable elements?
Simulations use
RANDOMvalues and run multiple scenarios to observe the range of possible outcomes.How can researchers use a simulation to refine a hypothesis?
Researchers can adjust variables in the simulation to test predictions before running real experiments.
Define simulation bias.
Simulation bias occurs when the assumptions or data used to build the simulation do not accurately represent the real system.
True or False?
Running a flawed simulation many more times will fix its inaccurate results.
False.
More runs reveal a wider range of outcomes but do not fix a flawed model.
A simulation can only be as accurate as the _____ and data it is built on.
A simulation can only be as accurate as the model and data it is built on.
