Question
Use the table of data from an investigation to answer the question.
Mass of ball (grams) Time to hit ground (seconds)
10 10.2
15 10.1
26 16.2
A student is investigating gravity and falling objects. She drops three balls and times how long it takes each ball to hit the ground. What is the most likely source of error? (1 Point)

if g is constant
get three values of g
h = (1/2) g t^2
so
g = 2 h/t^2
#1
g1 = ( 2/10.2^2) h = 0.01922 h
#2
g2 = (2/10.1^2) h = 0.01961h bigger g
#3
g3 = (2/16.2^2) h = 0.00762 h tiny g
well, I have a hunch that air friction is the problem. Big area means big friction force
Experiments one and two might be similar size and covering (leadpellets?) but experiment 3 seems to be a big beach ball with light weight for its diameter despite being more massive than the first two.

Answers:
1. She dropped the balls from different heights.
2. Perform a second trial.
