What is the momentum of torque?

What is the momentum of torque?

Torque can be defined as the rate of change of angular momentum, analogous to force. The net external torque on any system is always equal to the total torque on the system; in other words, the sum of all internal torques of any system is always 0 (this is the rotational analogue of Newton’s Third Law).

What is the moment of inertia of a yoyo?

Since a yo-yo is approximately a solid cylinder spinning about an axis through its center we can use the following formula to find its moment of inertia: I = 1 2 MR2 where M is the mass and R is the radius of the cylinder. The more mass away from the axis of rotation, the greater the yoyo’s moment of inertia.

Is angular momentum centrifugal force?

Angular momentum is a vector quantity (taken in the physical sense) of a mass’s rotational velocity about some axis. Centrifugal force is defined on the axis of a rotational reference frame, which depends on the inertia of the object.

How do you find momentum from torque?

By definition, torque τ = r × F. Therefore, torque on a particle is equal to the first derivative of its angular momentum with respect to time.

What is the relation between momentum and torque?

The torque is defined as the rate of change of angular momentum which is the same as the cross product of the linear force and the distance from the axis. So, the torque is the rate of change of angular momentum. We are given that the angular momentum is constant for a situation.

What is the moment of inertia of the Yo Yo about the contact point with the table?

The moment of inertia of the yo-yo about the contact point with the table is 2.1726 × 10-4 kg•m2.

What is angular momentum in chemistry?

The angular momentum vector that quantifies circular rotation of a particle about an axis is defined as the moment of the linear momentum, L = r× p, i. e. the vector product of the linear momentum and the radius vector from the point of rotation.
