U4 EDC: Egg Car Collisions

Criteria: How will you address the criteria with your car design? Which needs are associated with addressing the criteria?

Constraints: Which constraints will be the most challenging for your team based on your chosen criteria? Why?

What testing process do new cars go through to ensure the safety of its passengers? Describe how the law of inertia informs this process.

You will consider Newton's Laws and design your car before building it. Which of Newton's 3 Laws will have the biggest impact on the car design? Why?

Draw your initial prototype, either digitally or on paper, just click on the image icon

and insert a clear photo of your design.

What is the name of your car?

Use a scale to find the mass of your car in grams.

Insert 2 pictures of your built car, from the top-down and side view.

Evaluation:

What design features were effective during your testing to meet your criteria? Cite specific features. What alteration or modification had the most significant change during testing? Cite specific examples.

What design features address the inertia of the egg during the collision? Explain why.

What design features address the kinetic energy in the collision between the car and the wall? Remember KE = ½ m*v²

What design features use friction to their advantage when planning for the collision.

Redesign:

What changes must be made to improve your car? Include specific design features (if you are using a feature from another team, cite them as your source).

Insert 2 pictures of your car POST-Collision, from the top-down and side view.

Which of Newton's laws BEST describes why the crash dummy fell off the truck?

Why does the dummy keep moving after the car hits the barrier?

What determines a vehicle's crash worthiness? Check ALL that apply.

What vehicle safety features are critical to protecting people inside the vehicle? Check ALL that apply.
