Unit 2

Question 1

The longer an object is in the air, the farther it will fall.

Answer 1

IV: time in the air
DV: distance it will fall

Question 2

Horizontal Line

Answer 2

-pendulum lab
-y=1.1
-IV: amplitude
-DV: period (sec)
-c-value: period
-if c-value increases the line stays horizontal but moves up on the y axis
-as x doubles, y stays the same

Question 3

Linear

Answer 3

-Spring lab
-d=1.1m
-IV: mass (g)
-DV: stretch (cm)
-c-value: stretchiness
-if the stretchiness of the spring increased the line would get steeper
-as x doubles, y also doubles

Question 4

Quadratic

Answer 4

-Ball Bearing Lab
-B=0.2d^2
-IV: diameter (cm)
-DC: # of ball bearings
-small ball bearings had a large c-value and large ball bearings had a small c-value
-if C value were to increase the graph would get narrower
-when x doubles, y quadruples

Question 5

Inverse

Answer 5

-Paragraph lab
-L=36/w
-IV: width (cm)
-DV: length (cm)
-the c-value represents the area
-if the area of the paragraph was bigger the graph would be further from the origin
-when x doubles, y halves
