What do you mean by angular momentum?

Angular momentum is a vector quantity (more precisely, a pseudovector) that represents the product of a body’s rotational inertia and rotational velocity (in radians/sec) about a particular axis.

What is angular momentum in throwing and why is it important?

Just like linear momentum, angular momentum is conserved in the absence of external torques, which is why it is important. This means that ​an object spinning stays spinning​ in the absence of external torques, which is one of the central ideas of this lesson.

What is angular momentum proportional to?

Angular momentum of an object with linear momentum is proportional to mass, linear velocity, and perpendicular radius from an axis to the line of the object’s motion.

What is angular momentum in physics class 11?

Note Angular momentum is the rotational equivalent of linear momentum. Just as linear momentum equals the product of mass and velocity, angular momentum equals the product of angular mass (that is, a moment of inertia) and angular velocity. Thus, angular momentum = Moment of inertia × Angular velocity.

What is required to change the angular momentum of a system?

Angular momentum is changed by a net external torque, but not all forces cause a torque. To produce a torque τ, a force F must have a lever arm r and a component perpendicular to the lever arm.

What condition is required for the angular momentum of a system to be conserved?

zero
Angular momentum is conserved when net external torque is zero, just as linear momentum is conserved when the net external force is zero.

What is angular momentum in throwing?

Angular momentum can be defined as the movement of a mass when it is rotating or spinning. This is the movement of a mass around an object and is calculated by multiplying angular velocity with the moment of inertia.

How is angular momentum related to force?

If there is a net force, the momentum changes according to the impulse equation, and if there is a net torque the angular momentum changes according to a corresponding rotational impulse equation.

What is angular momentum in chemistry class 11?

How do you find angular momentum in physics?

Linear momentum (p) is defined as the mass (m) of an object multiplied by the velocity (v) of that object: p = m*v. With a bit of a simplification, angular momentum (L) is defined as the distance of the object from a rotation axis multiplied by the linear momentum: L = r*p or L = mvr.
