=media type="custom" key="10455212"Relation of Position and Time = PURPOSE: To find how Velocity is related to Position and Time

MATERIALS: Three bubble tubes, one blue, one green, one red, stack of books, stop watch and a flat surface.

PROCEDURE: Holding the tube vertically we waited until the bubble was at the bottom end of the tube before resting it diagonally on the counter and books so that the bubble would rise up toward the opposite end. Every time the bubble reached the bottom end of a tape strip the time was recorded. This procedure was repeated for each of the tubes. DATA: Blue Red Green

SAMPLE CALCULATIONS AND RESULTS:

CONCLUSIONS: Each tube traveled at a constant speed due to the positions and how fast the bubble traveled determined the time. The velocity is determined by how much time the bubble took in each position on each tube. The position, time and velocity are related because they all determine how much time it took from one end of each tube to the other.
