1. Free Fall Free Fall Examples
Motion of objects moving freely under the force of gravity
All objects falling near the surface of the earth accelerate at a constant rate of -9.8 m/s2 (neglecting air resistance)
You Know …
Vi = 0
a = g = +9.8m/s2 (make down +)
Free Fall Examples
A coin is dropped in a vacuum tube, find its displacement after .3 seconds. Find the coin's velocity after .3 seconds.
A rocket is fired vertically upward with an initial velocity of 29 m/s. Find its height and its total time in the air.
An object dropped on planet X falls 64 m in 4 seconds.  Find the acceleration due to gravity on planet X.
