5.2.2 Conservation of Angular Momentum The angular momentum is a vector defined as follows: (5.35)h→=r→×V→ The angular momentum vector is normal to the plane formed by the radius and velocity vectors and therefore normal to the plane of the orbit. If no external torque is applied, th...
A vectorc, depending on two other vectorsaandb, whose magnitude is the product of the magnitude ofa, the magnitude ofb, and the sine of the angle betweenaandb. Its direction is perpendicular to the plane throughaandband oriented so that a right-handed rotation about it carriesaintobthrough ...
Symmetry degree is utilized to characterize the asymmetry of a physical system with respect to a symmetry group. The scalar form of symmetry degree (SSD) based on Frobenius-norm has been introduced recently to present a quantitative description of symmetry. Here we present the vector form of the...

Since gravitational waves are solutions of Einstein's field equations with a zero stress-energy tensor, the reality of these waves was questioned. To demonstrate it, the momentum imparted to test particles by such waves was evaluated. A closed form expression for this quantity was provided by ...
Sections 2 gives analytical propagation expressions of three different BuG beams, respectively, where an autofocusing BuG beam in the case of (a1, a3) = (x/x0, y/y0) is emphatically studied. The evolution of the Poynting vector and angular momentum density for the autofocusing BuG beam ...

The energy E and angular momentum h (both per unit mass) defined as: Open image in new window are constants of the unperturbed motion. Hamilton's integral, which may be written in the form 1 : Open image in new window provides a further constant of the unperturbed motion under an ...
Force A acts 2 N west and 3 N south. Force B acts 5 N west and 2 N north. What is the resultant of these two vectors in unit vector form? What is the direction of a vector when divided by a scalar quantity? What two quantities are necessary for a vector quantity?
