How do you find the magnitude of angular momentum?

The magnitude of the angular momentum is found from the definition of the cross-product, l=rpsinθ, where θ is the angle between →r and →p. The units of angular momentum are kg⋅m2/s kg · m 2 / s .

Which of the following statements about angular momentum is correct?

This option is correct. Angular momentum is the product of moment of inertia and angular velocity. Therefore, it is clear that angular momentum will be directly proportional to the moment of inertia of the object.

What is the magnitude of the angular momentum of the bar?

The magnitude of the angular momentum is 3.477 kg•m2/s.

What is the direction of the angular momentum in Part A )?

angular momentum: A vector quantity describing an object in circular motion; its magnitude is equal to the momentum of the particle, and the direction is perpendicular to the plane of its circular motion.

What is L in angular momentum?

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.

Which of the following is equal to the time rate of change of angular momentum?

The vector sum of all torques acting on a particle is equal to the time rate of change of the angular momentum of that particle.

What is statement the moment of momentum?

Moment of momentum measures an objects tendency to continue to spin, it describes the rotary inertia of a system in motion about an axis.

Is RPM angular velocity?

Revolutions per minute can be converted to angular velocity in degrees per second by multiplying the rpm by 6, since one revolution is 360 degrees and there are 60 seconds per minute. If the rpm is 1 rpm, the angular velocity in degrees per second would be 6 degrees per second, since 6 multiplied by 1 is 6.
