3.3 Freely Falling Objects
STANDARDS
I can interpret and analyze the motion of an object in free fall.
3.1
Free Fall is the motion of an object falling freely under the influence of gravity.
EquationsEquation
v = vo + g t
x = xo + vo t + ½ g t2
v2 = vo2 + 2 g Δ x

ExampleA ball is thrown straight upward at 15.2 m/s. What is the maximum height that the ball will reach?
You drop a rock from a bridge to the river below. When the rock has fallen 4 meters, you drop a second rock. As the rocks continue their free fall, does their separation increase, decrease, or stay the same?
FALLING STONES
Purpose: Calculate human reaction time using free fall and the acceleration due to gravity.
How Fast? Data:1. Create a data table
and record the dropping distance for 10 trials of catching the ruler.

Calculations:1. Calculate your average dropping
distance.2. Use your average dropping
distance, and the acceleration due to gravity, to calculate your average reaction time.
