Experiment topics:
• Displacement-time graphs
• Linear gradients
• Velocity
Set of equipment for investigating the concept of velocity by means of student experiments. Consisting of three small coloured plastic tubes in which an air bubble rises at constant velocity in a viscous liquid, provided the tubes are aligned vertically. Since the viscosities differ, the velocities also differ. The position of the air bubble is plotted against time. The three different resulting straight lines lead to a definition of velocity.
Length: 500 mm approx.
Diameter: 13 mm approx.
