In honor of Computer Science Education Week we have a challenge:

Try using JavaScript to draw picture. The best drawing wins candy.

The sample page can be found here:

]]>It was gathered Felix Baumgartener fell from space to earth. On the screen will be lots of data to help us understand what was happening during this. Don’t watch the whole video, just see the first 15 seconds or so and observe what the data is telling us.

On a seperate sheet of paper please answer the included questions.

1. What is happening to the altitude?

2. What is happening to his velocity?

3. Calculate his velocity at 3 points in the fall? Show your work. Either capture amplitude data and time data, or calculate the conversion from km/hr.

4. What is his acceleration? Use the velocities from question 3. Graph this (velocity is dependent variable; time is dependent) and find the slope of that graph. (Use Excel or Google Sheets.)

5. Given his initial height and our data, how long should it take him to reach the height at which he releases the parachute (2600 m)? *Edit the computer model below to find the time.*

6. If your model is not exactly correct, theorize factors that it might have taken into account for.

7. What happens to his velocity after the parachute is released and why?

]]>Use the video below to answer the question.

We’re going to look more closely at the motion of something moving. The video below has tape marks every 10 cm. Use the video to gather data about the trajectory of the ball as it falls. It is in 8x slow motion, so each 8 seconds passed on the video equates to 1 second in reality.

Please use either Excel or Google Sheets to graph the data you gathered.

Next we're going to use a programming language called NetLogo to edit a bad computer model to fit the data that we gathered.

The model below is of the motion of the ball in freefall. Please edit it to better fit our experimental data.
