Description
The Constant Velocity 5-Tube Set consists of five transparent plastic tubes filled with liquid. These are simple devices that students can use to generate position vs. time data to explore constant motion and improve their graphing skills. Four of the tubes contain colored oils of three different viscosities. A bubble of air in each tube rises at a constant velocity that is determined by the viscosity of the liquid, the angle at which the tube is inclined, and the temperature. The fifth tube contains a colorless oil and two balls — one plastic and one steel. A magnet is also included to hold and release the balls.
