Net Torque: Calculating Momentum & Time

Click For Summary

Discussion Overview

The discussion revolves around the concept of net torque, its relationship to angular momentum, and the effects of net torque on an object's motion. Participants explore the definitions and formulas related to torque and angular momentum, as well as the implications of applying net torque.

Discussion Character

  • Exploratory
  • Technical explanation
  • Conceptual clarification

Main Points Raised

  • One participant inquires about the formula for net torque, drawing a parallel to the relationship between net force and momentum.
  • Another participant clarifies that net torque is defined as the change in angular momentum divided by time.
  • A question is posed regarding the relationship between angular momentum, angular velocity, and mass, with a request for correction if the understanding is flawed.
  • Further clarification is provided that angular momentum can be expressed as the product of angular velocity and angular inertia, with a note that angular inertia is dependent on mass distribution.
  • A participant expresses gratitude for the assistance received in understanding the concepts discussed.

Areas of Agreement / Disagreement

The discussion includes multiple viewpoints regarding the definitions and relationships of torque and angular momentum, with no consensus reached on all aspects. Participants are exploring and clarifying their understanding rather than establishing definitive conclusions.

Contextual Notes

There are unresolved aspects regarding the precise definitions and relationships between angular momentum, angular velocity, and mass, as well as the effects of net torque on motion.

is there any formula of net torque? as we know, net force = momentum / time right? what about net torque?
 
Physics news on Phys.org
Net force is change in momentum divided by time. Net torque is change in angular momentum divided by time.
 
So, angular momentum = change in angular velocity x mass?

Please correct me if I'm wrong. Then, if net torque is applied, an object will experience a constant angular speed or an angular acceleration ?
 
Ok. I get it now. Thanks for your help. =)
