Today we finished testing our bumper/airbag systems and began working on the project poster.

Today you should have completed testing on your airbag/bumpers. The next step is to update the V&V report with your data/conclusions. We will have time on Monday after break to update the reports.
Today we created a force graph for our landers hitting the ground and determined the impulse, impact time, average force, max force, max acceleration, and number of g's. Then we started building airbags and bumpers to try to decrease the max force and increase the impact time for a safer landing.
Today we found how much force will crack an egg (about 35 Newtons). We also looked at impulse and momentum and talked about how these concepts will help us to design a bumper for our lander. Tomorrow we will use the force plate to create a force graph for the lander without and with a bumper to see the difference.
Today we finalized the report sections dealing with parachute design. Make sure your draft report is in the physics folder on google drive, otherwise you won't get credit for it.
Today we talked about how we are going to communicate our findings in this project. We will be writing a technical report for NASA to prove that our design will allow a lander to successfully land on Mars. We began by looking at a sample NASA V&V report to understand the content and sections of the report. Then you began writing a draft of the sections that involve your parachute design.
Today we analyzed the videos of the landers falling from the balcony and created postion vs time and velocity vs time graphs. You should be able to determine the terminal velocity of your lander from your graphs. Finish answering the questions on the back of the project log for Monday. On Monday we will begin working on the V&V report, which will include your graphs and data and information from your project logs.
Today we discussed the results of our investigation into what affects terminal velocity. You then built parachutes for your landers and began thinking about how you would measure the terminal velocity of your lander. Tomorrow we will determine the terminal velocity of our landers and being drafting sections for the final Verification and Validation report.
Yet another snow day. Enjoy your day off. See you tomorrow!
Enjoy your day off! We will build parachutes tomorrow.
