1. Design a device that minimizes the force on a macroscopic object during a collision. (i.e. incorporate the concept that for a given change in momentum, force in the direction of the change in momentum is decreased by increasing the time interval of the collision ; and make use of the principle above so the device has the desired effect of reducing the net force applied to the object by extending the time the force is applied to the object during the collision).
2. Describe the scientific rationale for choice of materials in a design plan for a device that minimizes the force on a macroscopic object during a collision, and for the structure of the device.
3. Describe the criteria and constraints, along with the tradeoffs in design solutions that minimize a force on an object during a collision (e.g. constraints: cost, mass, the maximum force applied to the object, and requirements set by society for widely used collision-mitigation devices such as seatbelts, football helmets).
4. Test and evaluate the device based on its ability to minimize the force on the test object during a collision.
5. Identify any unanticipated effects or design performance issues exhibited by a device that minimizes the force on a macroscopic object during a collision.
6. Use the test results to improve the performance of a device that minimizes the force on a macroscopic object during a collision (e.g. extending the impact time, reducing the device mass, and/or considering cost-benefit analysis).
