Question

You've made the hypothesis that the steeper the slope, the faster a ball will be rolling when it reaches the bottom.

What should be your independent variable in an experiment testing this hypothesis?
A. how heavy the ball is
B. how steep the slope is
C. how high the ball starts on the slope
D. how fast the ball is rolling at the bottom

Answer 1

The answer is b, how steep the slope is

Step-by-step explanation:

The independent variable is the one that you change or control, you need to control how steep the slope is in order to find out if the ball goes faster
