Question

Real World Modeling Models can be an effective tool when decisions need to be made quickly and visualizing expected results is important. When we actually test a model, we are running a simulation. For this science journal, your task is to answer Part A and Part B with a claim statement and support it with evidence and reasoning. You can put both answers in a text box, annotate on the doc below, or use this word doc and upload it to submit. Mars Exploration Rover Landing System The landing system for the Mars Explorations Rover spacecraft used a system of air bags to protect its fragile rover during landing. Engineers first used a computer simulation to test the new air bag design; then they used crash tests with various types of vehicles. Part A: Describe one benefit of using a computer simulation to test the air bag design before conducting crash tests. Part B: Explain how crash tests help engineers test the air bag design.

Answer 1

One benefit of using a computer simulation for testing the air bag design is the ability to visualize expected results. Crash tests provide real-world validation and verification of the air bag design.

Part A: One benefit of using a computer simulation to test the air bag design before conducting crash tests is that it allows engineers to quickly and easily visualize the expected results of different design scenarios. Through the simulation, engineers can modify and fine-tune the air bag design to optimize its effectiveness in protecting the rover, without the need for physical prototypes and extensive testing.

Part B: Crash tests help engineers test the air bag design by providing real-world validation and verification of its performance. By subjecting the designed air bags to actual impact forces and studying their behavior, engineers can assess whether the air bags provide sufficient protection and whether any further design improvements are needed.
