Converting units for angular motion

Click For Summary
SUMMARY

Angular velocity is definitively measured in radians per second (Rad./sec.), which are the standard SI units. When multiplying angular velocity by the radius in meters, the result is the instantaneous tangential velocity expressed in meters per second (m/s). Torque is measured in Newton-meters (N*m), and angular velocity cannot be expressed in square meters per second (m^2/s) as it must maintain its units of angular measure per time.

PREREQUISITES
  • Understanding of angular motion concepts
  • Familiarity with SI units of measurement

  • Knowledge of the relationship between angular velocity and tangential velocity
NEXT STEPS
  • Study the relationship between angular velocity and tangential velocity in detail
  • Learn about the mathematical derivation of torque and its implications
  • Explore the concept of rotational dynamics and its applications
  • Investigate the use of radians in various physical calculations
USEFUL FOR

Physics students, mechanical engineers, and anyone interested in the principles of angular motion and its applications in real-world scenarios.

I think angular velocity can be measured in radians/second. I also heard that if I multiply a value of angular velocity that is in the units of Rad./sec. by a certain value of radius in meters, I will get m/s, but this is the instantaneous tangential velocity.

Is any of these right?

In addition, since torque is measured in N*m (cross product or something, don't quite get it), does this mean that angular velocity can be measured in m^2/s and not be instantaneous and tangential?

Yes. Those are the SI units of angular velocity.

Yes the instantaneous speed of a particle is the product of its angular velocity (in radians per second) and its distance from the axis of rotation.

No. Just based on the units that is not possible. Angular velocity must have units of [some angular measure]/[time]
