Your general comment

Will a steeper ramp give greater or lesser time?

I think the ramp with the steepest slope will have the least time interval.

As slopes increases will time intervals increase, decrease or show no pattern?

I think the times would decrease as the slope increased.

Do your results support or fail to support your hypothesis about increasing or decreasing times?

I support my hypothesis that the steeper slopes took the least amount of time. As one can see in these data, the times intervals were much shorter in trials with three dominos in comparison to those with one.

How do you think ave velocity is related to slope?

I think the average velocity of the ball was greater when the slope of the ramp was steeper.

Speculate on why ave velocity changes with slope.

I think the average velocity corresponds with the slope, and they are the same thing.

How could you test your speculations?

We could test out different slopes with different velocities. Also we could compare the formula for average velocity to the slope.
