SUMMARY

The discussion centers on the preference for using radians per second (rad/s) over revolutions per minute (rev/min) in physics and engineering contexts. Participants confirm that radians per second is the standard unit for angular velocity, emphasizing its widespread acceptance among physicists. While some engineering fields may use various conventions like RPM or CPS, the consensus is that adopting rad/s is beneficial for clarity and consistency in scientific calculations.

PREREQUISITES
  • Understanding of angular velocity and its units
  • Familiarity with basic physics concepts
  • Knowledge of unit conversion between rad/s and rev/min
  • Awareness of engineering conventions in measurement
NEXT STEPS
  • Research the differences between rad/s and rev/min in practical applications
  • Learn about unit conversion techniques in physics
  • Explore the significance of using standard units in scientific communication
  • Investigate various engineering conventions for measuring angular velocity
USEFUL FOR

This discussion is beneficial for physics students, engineering professionals, and anyone interested in understanding the importance of standard units in scientific measurements.

According to the equations for angular, linear velocity and acceleration, it is in rad/s. So, for my own mindset, I always change everything to rad/s. (As opposed to rev/min or something) And now it's a habit, like reducing fractions. I didn't understand what we were doing very well for some reason, so that may be part of it. We don't do much work in my physics class, so it's easy to get lost. :P
Is this bad to do? Or at least annoying in the real science world? Because if it is unnecessary or annoying, then I shall stop. What do physicists/engineers/whatever use? My teacher said he wasn't sure, but the answer book took both answers.

Using everything in common units is fine in almost all walks of life, especially textbook cases.

In engineering you get all sorts of very odd numbering conventions. You will find one company always uses RPM and others use rad/s. I've even seen Rev/s, and CPS used.

Almost without exception, physicists use radians/second. You probably can't go wrong in physics using this convention.
