Total questions: 39
Worksheet time: 20mins
Computer modelling is:
the use of computers to simulate real-world systems or processes
the physical construction of computer hardware
the manual drawing of diagrams to represent systems
the programming of games for entertainment purposes
The advantages and disadvantages of using models include:
They help simplify complex systems but may not capture all real-world details.
They always provide accurate predictions for every scenario.
They eliminate the need for any real-world testing.
They are only useful in theoretical studies and not in practical applications.
Identify real-life examples of modelling applications.
Weather forecasting
Playing video games
Listening to music
Reading a novel
Simulations are created and used in which of the following ways?
