Distance it takes for terminal velocity

Click For Summary
SUMMARY

The discussion centers on calculating the distance required for an object, such as a sphere or ball bearing, to reach terminal velocity in a viscous liquid, specifically in the context of Stokes' Law. It is clarified that the motion does not involve constant acceleration, thus invalidating the use of SUVAT equations for this scenario. Participants are directed to a relevant lecture on drag for further insights.

PREREQUISITES
  • Understanding of Stokes' Law and its applications in fluid dynamics
  • Knowledge of terminal velocity concepts in viscous fluids
  • Familiarity with drag forces and their impact on falling objects
  • Basic principles of kinematics, particularly regarding acceleration
NEXT STEPS
  • Research the mathematical derivation of Stokes' Law
  • Explore the concept of drag coefficients in different fluids
  • Learn about terminal velocity calculations in non-constant acceleration scenarios
  • Investigate experimental designs for measuring terminal velocity in viscous liquids
USEFUL FOR

Students and researchers in physics, engineers designing experiments involving fluid dynamics, and anyone interested in the principles of motion in viscous environments.

Hi, i just wondered if it is possible by calculation to determine how far in a viscous liquid it would take for an object (sphere, ball bearing) to reach terminal velocity. I have to design an experiment to investigate Stokes law. Could i use suvat equations as it is constant acceleration?

Thanks

Unfortunately it is not constant acceleration.

Here is an interesting lecture on drag that you might benefit from:
