ball down ramp

Your 'ball down ramp' report has been received. Scroll down through the document to see any comments I might have inserted, and my final comment at the end.

Your general comment

Will a steeper ramp give greater or lesser time?

THe interval for the ball to roll down the steepest ramp will be less because it will be going faster at the end of the steepest ramp

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

The time intervals woud decrease as the slope increased

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

THey were just as I though increase slope decrease interval

How do you think ave velocity is related to slope?

As the angle of the shelf changes the velocity change with the I think with the tangent of the angle of the shelf to the table

Speculate on why ave velocity changes with slope.

There is less resistance to the gravitional force on the ball as the angle of the shelf increases

How could you test your speculations?

We could repeat the experiment with more extreme angles or find a way to take the gravity away and repeat
