Question

A science class was investigating how far a ball would roll down a ramp that had been set at different angles. The table below shows their results.



Trial

Angle of Ramp

Distance traveled (m)

1

50o

10.2

2

45o

12.3

3

40o

9.5



Controlled scientific experiments include variables. One kind of variable is an independent variable (test variable) and the other kind is a dependent variable (outcome variable.) Which statement correctly identifies the variables for this experiment?



A The angle of the ramp is the independent variable, and the dependent variable is the distance traveled.

B The angle of the ramp is the independent variable, and the dependent variable is the size of the ball.

C The distance traveled is the independent variable, and the dependent variable is the weight of the ball.

D The distance traveled is the independent variable, and the dependent variable is the angle of the ramp.

Answer 1

Explanation:

the distance traveled is the independent variable, and the dependent variable is the angle of ramp
