 # Is Angular Momentum A Pseudo Vector?

## What is axial vector give example?

An example of an axial vector is the vector product of two polar vectors, such as L = r × p, where L is the angular momentum of a particle, r is its position vector, and p is its momentum vector.

Compare pseudo-scalar.

## Is Vector a current?

Note: Current is a vector because it has a magnitude and a direction. But the thing is a vector always obeys the law of addition of vectors. Since current doesn’t obey it and it follows algebraic addition, currents are scalar.

## Can the resultant of two vectors be zero?

Yes, two vectors of equal magnitude that are pointing in opposite directions will sum to zero. Two vectors of unequal magnitude can never sum to zero. If they point along the same line, since their magnitudes are different, the sum will not be zero.

## What is the difference between polar vector and axial vector?

Polar vector A vector quantities whose direction is along the direction of the motion of a body or particle is known as polar vector E.g: displacement, velocity etc Axial vector A vector quantities whose direction is along the direction of rotation of the body or particle E g: angular acceleration,torque etc.

## What is angular momentum principle?

Principle of conservation of angular momentum states that, If no external torque acts on a system, the total angular momentum of the system remains constant. If I be the moment of inertia of a body about a given axis of rotation and w be its angular velocity, then I w = constant.

## What type of vector is angular momentum?

First, the L vector represents the angular momentum—yes, it’s a vector. Second, the r vector is a distance vector from some point to the object and finally the p vector represents the momentum (product of mass and velocity).

## Is angular momentum is a scalar?

The spin angular momentum vector of a rigid body is proportional but not always parallel to the spin angular velocity vector Ω, making the constant of proportionality a second-rank tensor rather than a scalar….Angular momentumDerivations from other quantitiesL = Iω = r × pDimensionM L2T−14 more rows

## Is angular momentum a polar vector?

The velocity vector is a displacement vector (a polar vector) divided by time (a scalar), so is also a polar vector. … Angular momentum is the cross product of a displacement (a polar vector) and momentum (a polar vector), and is therefore a pseudovector.

## Is work a vector quantity?

Complete answer: Also, we know that work is a dot product of vectors force and the displacement. Since, the dot product is a scalar quantity. So, work is a scalar quantity, it has only magnitude not direction.

## Is angular momentum a torque?

In US mechanical engineering, torque is defined mathematically as the rate of change of angular momentum of an object (in physics it is called “net torque”). The definition of torque states that one or both of the angular velocity or the moment of inertia of an object are changing.

## How is angular momentum calculated?

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.

## Is angular momentum an axial vector?

Axial vectors are those vectors which represent rotational effect and act along the axis of rotation. Eg: Angular velocity, torque, angular momentum etc are axial vectors.

## What is angular momentum equal to?

Angular momentum is defined, mathematically, as L=Iω, or L=rxp. This equation is an analog to the definition of linear momentum as p=mv. Units for linear momentum are kg⋅m/s while units for angular momentum are kg⋅m2/s.

## Is angular momentum scalar or vector?

Angular momentum is a vector quantity that represents the product of a body’s rotational inertia and rotational velocity about a particular axis. The angular momentum is the product of the moment of inertia and the angular velocity around an axis.

## Is angular momentum a force?

Momentum is a vector, pointing in the same direction as the velocity. … Angular momentum is also a vector, pointing in the direction of the angular velocity. In the same way that linear momentum is always conserved when there is no net force acting, angular momentum is conserved when there is no net torque.

## What is the difference between linear and angular momentum?

Angular momentum is inertia of rotation motion. Linear momentum is inertia of translation motion. The big difference is that the type of motion which is related to each momentum is different. It is important to consider the place where the force related to rotation applies, which is appears as ‘r’ in the formula.

## Is torque a vector?

Torque is a measure of the force that can cause an object to rotate about an axis. … Torque is a vector quantity. The direction of the torque vector depends on the direction of the force on the axis.
