Answer
The usefulness of simulation as an experimental tool are;
• It provides a convenient way to test and explore the various ‘what-if’ cases.
• It captures more details thus increases accuracy and precision.
• Simulation models can present uncertainty.
Explanation
Simulation is applied in experiments because it can facilitate analysis of result in a safe and efficient manner. Simulation uses models that allow digital presentation of results in both 2D and 3D. In experiments where visual presentations are carried, simulation is employed because it takes less time and the costs involved are lower.
