Angry Birds

Rhett Allain's Dot Physics post The Physics of Angry Birds

Your task

Measure the acceleration due to gravity in the Angry Birds world. Using g as a calibration, determine the height of the slingshot in meters.

Instructions

1. Set the scale using a Calibration Stick and the height of the slingshot. Set the value of the height of the slingshot to 1.

2. Uncheck Fixed Origin, Fixed Angle, and Fixed Scale.

3. Create a new coordinate pair.

4. In each frame, adjust the coordinate pair so that it is fixed on stationary points.

5. Mark the angry bird while it is in the air.

6. Measure the y-acceleration of the bird in units of "slingshots per second squared".

7. Assuming that the y-acceleration has a magnitude of 10 m/s², calculate the height of the slingshot in meters.

8. Measure the diameter of the bird and calculate its diameter in meters.
