Initial Verbal Description

The high incline BB was faster than the low incline BB. The BB rolled at a constant speed.

The BB on the high/low incline rolled down a tube starting at position 0. On the low incline, it moved in the positive direction with a constant velocity of 6.3 cm/beat for 18 beats. The BB on the high incline rolled in the positive direction with a constant velocity of 11.4 cm/beat for 10 beats.
