Net Torque: Calculating Momentum & Time

Click For Summary
SUMMARY

Net torque is defined as the change in angular momentum divided by time, analogous to how net force is the change in momentum divided by time. Angular momentum is calculated as the product of angular velocity and moment of inertia, with moment of inertia being dependent on the mass distribution within an object. When net torque is applied, an object will experience angular acceleration, leading to a change in angular speed. This discussion clarifies the relationships between net torque, angular momentum, and angular inertia.

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. =)
