Net Torque: Calculating Momentum & Time

In summary, net torque is the change in angular momentum divided by time, similar to how net force is the change in momentum divided by time. Angular momentum is calculated by multiplying angular velocity and angular inertia, which is determined by the distribution of mass within an object. An object experiencing net torque will either have a constant angular speed or an angular acceleration. Additional information can be found on Wikipedia under the articles "Moment of Inertia" and "List of Moments of Inertia."

is there any formula of net torque? as we know, net force = momentum / time right? what about net torque?

Net force is change in momentum divided by time. Net torque is change in angular momentum divided by time.
 
  • #3
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. =)
 

1. What is net torque?

Net torque is the measure of the rotational force on an object. It is calculated by multiplying the magnitude of the force applied to the object by the distance between the force and the object's center of mass.

2. How is net torque different from regular torque?

Regular torque refers to the rotational force on an object caused by a single force. Net torque, on the other hand, takes into account multiple forces acting on an object and their combined effect on its rotational motion.

3. How do you calculate net torque?

To calculate net torque, you need to determine all the forces acting on an object, find their individual torques by multiplying the force by the distance from the center of mass, and then add them together. The resulting sum is the net torque on the object.

4. What is the relationship between net torque and momentum?

The net torque acting on an object can change its rotational motion, which in turn affects its angular momentum. As the net torque increases, the angular momentum of the object also increases.

5. How does time affect net torque?

Time does not directly affect net torque, as it is a measure of force and distance. However, the amount of time a force is applied to an object can impact the magnitude of the net torque and therefore affect the object's rotational motion.
