Angular Momentum: Single Particle01:10

Angular Momentum: Single Particle

6.6K
Angular momentum is directed perpendicular to the plane of the rotation, and its magnitude depends on the choice of the origin. The perpendicular vector joining the linear momentum vector of an object to the origin is called the “lever arm.” If the lever arm and linear momentum are collinear, then the magnitude of the angular momentum is zero. Therefore, in this case, the object rotates about the origin such that it lies on the rim of the circumference defined by the lever arm...

First Law: Particles in One-dimensional Equilibrium

7.1K
Newton's first law of motion states that a body at rest remains at rest, or if in motion, remains in motion at constant velocity, unless acted on by a net external force. It also states that there must be a cause for any change in velocity (a change in either magnitude or direction) to occur. This cause is a net external force. For example, consider what happens to an object sliding along a rough horizontal surface. The object quickly grinds to a halt, due to the net force of friction. If...

Principle of Linear Impulse and Momentum for a Single Particle01:20

Principle of Linear Impulse and Momentum for a Single Particle

841
Linear momentum is a fundamental concept in physics that describes the motion of an object. It is a vector quantity, having a magnitude equal to the product of its mass and its velocity, and direction along the object's velocity. On the other hand, linear impulse, also known as momentum impulse, is a concept in physics related to the change in the linear momentum of an object. Impulse is a vector quantity defined as the product of force and the time over which the force is applied.

Impulse-Momentum Theorem00:49

Impulse-Momentum Theorem

12.3K
The total change in the motion of an object is proportional to the total force vector acting on it and the time over which it acts. This product is called impulse, a vector quantity with the same direction as the total force acting on the object.
By writing Newton's second law of motion in terms of the momentum of an object and the external force acting on it, and simultaneously using the definition of the impulse vector, it can be shown that the total impulse on an object is equal to its...

First Law: Particles in Two-dimensional Equilibrium

5.2K
Recall that a particle in equilibrium is one for which the external forces are balanced. Static equilibrium involves objects at rest, and dynamic equilibrium involves objects in motion without acceleration; but it is important to remember that these conditions are relative. For instance, an object may be at rest when viewed from one frame of reference, but that same object would appear to be in motion when viewed by someone moving at a constant velocity.
Newton's first law tells us about...

Angular Momentum and Principle Axes of Inertia

290
The concept of angular momentum for a solid structure is illustrated as the cumulative result of the cross-product of the position vector of the mass element and the cross-product of the body's angular velocity with the position vector.
To put this equation into simpler terms, it can be reconfigured using rectangular coordinates. This involves choosing an alternative set of XYZ axes that are arbitrarily inclined with respect to the reference frame. The process of deriving the rectangular...

Area of Science:

  • Optics and Photonics
  • Condensed Matter Physics

Background:

  • Near-zero index (NZI) materials exhibit a phase refractive index close to zero.
  • Light-matter interactions are typically explained by energy considerations, neglecting momentum.
  • The Abraham-Minkowski debate concerns the momentum of light in dispersive media.

Purpose of the Study:

  • Investigate the role of momentum within NZI materials.
  • Analyze momentum exchange in epsilon-and-mu-near-zero (EMNZ), epsilon-near-zero (ENZ), and mu-near-zero (MNZ) materials.
  • Clarify fundamental radiative processes and light-matter interactions in NZI materials.

Main Methods:

  • Theoretical analysis of light momentum (Abraham and Minkowski forms) within NZI materials.
  • Examination of momentum recoil, transfer, and Doppler shift.
  • Application of momentum considerations to radiative processes and diffraction phenomena.

Main Results:

  • Minkowski-canonical momentum is zero in all NZI materials.
  • Abraham-kinetic momentum is zero in ENZ and MNZ materials, but non-zero in EMNZ materials.
  • Momentum recoil, transfer, and Doppler shift are inhibited in NZI materials, explaining process inhibition and absence of diffraction.

Conclusions:

  • Momentum considerations are crucial for understanding light-matter interactions in NZI materials.
  • Inhibition of momentum-related phenomena in NZI materials impacts fundamental processes.
  • Findings offer insights for nanoscale light-matter interactions and advanced lasing applications.
