We watched more videos to give examples and depth to our study of air resistance and had some notes on what influences air resistance. To sum it up:
Factors influencing air resistance:
-Size of object: greater size encounters more air - specifically the size of the object perpendicular to the direction of motion.
-Shape of the object: how air must move around the object and action-reaction forces involved in making air move
- Air density - more dense air --> more matter encountered by object per second
-velocity of object relative to air - more difference in velocities --> more matter encountered by object per second.
We analyzed air resistance of a falling object until velocity increases to equal gravity's pull: terminal velocity, when acceleration = 0 and the object falls at its maximum, constant velocity.
Much discussion was involved in different classes:
Skydiving to break the sound barrier and a world record (apparently hasn't been broken yet)
Aptera - awesome aero, so why not in production yet? (some interesting conspiracy theories out there as to what the heck happened)
other fun aero cars
