Exam points

  • choose timing markers after release so the falling ball is at terminal velocity
  • identify mass, fluid density or related measurements needed to calculate viscosity

1.4.26 - Core Practical 2 - viscosity by falling-ball method question 1

[Maximum number: 1]

A student determines the terminal velocity of a ball bearing as it falls through oil. He releases the ball bearing at point V and measures the time taken for it to fall a measured distance.
