FREE FALL

FREE FALL. Freely falling objects are affected only by gravity (assuming no air resistance.) Acceleration of gravity g = 9.8 m/s 2. Instantaneous speed = acceleration x elapsed time v = g x t For an object falling from rest.

  1. FREE FALL

  2. Freely falling objects are affected only by gravity (assuming no air resistance.) • Acceleration of gravity g = 9.8 m/s2

  3. Instantaneous speed = acceleration x elapsed time v = g x t For an object falling from rest

  4. For objects thrown upward, speed decreases at the same rate as it increases when moving downward, 9.8 m/s2.

  5. At the point where it changes direction from upward to downward, its instantaneous speed is zero.

  6. Distance, d, an object moves at the end of time, t d = ½ gt2
