Will changing the height of a ramp change the average velocity of a toy car?

Will changing the height of a ramp change the average velocity of a toy car?
Yes, because if the average velocity for a car on a ramp at 17 degrees is 1.727(m/s), and if you change the degrees of the ramp, you change all the data points that were gathered to get 1.727.
If that was to hard then

Yes

It will change the V.
