SC SC11.2.4, part of SC Materials: Unless a demonstration of free fall motion is desired, this lesson requires only the attached worksheet, pencils, and calculators.

Lesson: How is free fall motion applicable to exciting activities and events, such as skydiving? This lesson covers (or may cover with minimal addition discussion) the following Wyoming State Standards and requires approximately 55 minutes. Take Away Message: Even something as awesome as Felix s jump requires a deep understanding of physics to properly execute and understand. Unlike friction, air drag (or air resistance) depends upon velocity. Air drag The force (or forces) that act upon a moving object opposite to that object s direction of travel. Gravity The phenomenon that causes bodies to attract with a force related to their relative locations and masses. Velocity The speed and direction of an object, quantified as a vector.

Acceleration The rate at which the velocity of an object is changing. Free fall motion Motion of an object caused solely by the force of gravity acting upon that object. Students may benefit from learning about these prior to the lesson, perhaps as a homework assignment. Vocabulary: These words are interesting and important words or phrases found throughout this lesson. More images are available online.Ģ Concepts: The following concepts apply to this lesson: free fall motion, acceleration, velocity, gravity, air drag, model development, and potential model flaws. The following image is of Felix just after jumping from his capsule. Also, a discussion about approximations or assumptions would be a good lead-in to this lesson. Starting height: 39,045 m Starting velocity: 0 m/s (although this is not true since Free fall duration: 4 minutes 19 seconds the balloon was actually rising when he jumped) Maximum absolute speed: 1,342.8 km/hr Acceleration due to gravity: 9.81 m/s 2 Speed of sound (at sea level): m/s Time Felix reached the speed of sound: 34 seconds Total flight time: 9 minutes 9 seconds Notice that some unit conversions will be required if the data is taken as given here. The following statistics are those used in the included worksheet, and can be used to develop additional questions and discussions beyond what is included here. Additionally, the showing of a YouTube video of the jump is a great add-on to this lesson. While, at the time of this lesson s writing, the details of his jump were either not entirely available, or inconsistent across various sources, his jump does provide a prime case for analysis of free fall motion. Background: Felix Baumgartner, a Redbull athlete, recently made a free fall jump from the upper atmosphere. This applies to high school physics and/or algebra. An emphasis is placed on thinking about and logically analyzing the results. Computations to find velocity and acceleration are made. This lesson capitalizes on that fact, and the recent free fall jump made by Felix Baumgartner from 39,045 meters. 1 Free fall from SPACE! Description: A major theme in physics is free fall motion.
