Vector field p∇ S{\displaystyle\mathbf{p}=\nabla S} is conservative vector field.
For this purpose we useNewton's notation for the time derivative A˙{\displaystyle{\dot{\mathbf{A.
To see this, consider the unit normal n^{\displaystyle\mathbf{\hat{n}}} in the right side of the equation.
All physical quantities are defined this way at each instant of time, in the current configuration,as a function of the vector position x{\displaystyle\\mathbf{x.
The law is also written more famously as F m a{\displaystyle\mathbf{F}=m\mathbf{a}} since m is a constant in Newtonian mechanics.
It has a charge of q'=-qR/p and lies on a line connecting the center of the sphere and the inner charge at vector position( R 2/ p 2)p{\displaystyle( R^{ 2}/ p^{ 2})\ mathbf{p.
Hence we arrive at∇⋅ g-4 π G ρ,{\displaystyle\nabla\cdot\mathbf{g} =-4\pi G\rho,} which is the differential form of Gauss's law for gravity.
The Lorentz force has the same form in both frames, though the fields differ, namely:F q.{\displaystyle\mathbf{F}=q\left.} See Figure 1.
The components X i{\displaystyle\ X_{i}}of the position vector X{\displaystyle\\mathbf{X}} of a particle, taken with respect to the reference configuration, are called the material or reference coordinates.
A Lie algebra L is defined to be nilpotent if and only if the lower central series defined recursively by L 0 L,L i+ 1{\displaystyle\mathbf{L}^{0}=\mathbf{L},\quad\mathbf{L}^{i+1}=\} eventually reaches{0.
Given vectors a, b and c,the product a∧ b∧ c{\displaystyle\mathbf{a}\wedge\mathbf{b}\wedge\mathbf{c}} is a trivector with magnitude equal to the scalar triple product, and is the Hodge dual of the scalar triple product.
The wave function is a function of the two electron's positions: ψ ψ( r 1, r 2).{\displaystyle\psi=\psi(\mathbf{r}_{1},\mathbf{r}_{2}).} There is no closed form solution for this equation.
Angular momentum is always split into orbital L, spin S and total J:J L+ S.{\displaystyle{\mathbf{J}}={\mathbf{L}}+{\mathbf{S}}.} Given that in quantum mechanics, angular momentum is quantized and there is an uncertainty relation for the components of each vector, the representation turns out to be quite simple although the background mathematics is quite complex.
They have devised a concept known as"fictitious magnetic currents" usually denoted by M, and defined as M 2E a p e r× z^{\displaystyle~~\mathbf{M}~=~2\mathbf{E}^{aper}~\times~\mathbf{\hat{z.
The magnitude of the acceleration therefore follows an inverse square law:| a|G M x 2.{\displaystyle|\mathbf{a}|={\frac{ GM}{ x^{ 2}}}.} The potential associated with a mass distribution is the superposition of the potentials of point masses.
While the contribution to the Earth's gravitational field from this quadrupole is extremely important for artificial satellites close to Earth, it is less important for the Moon because the 1| R|3{\displaystyle{\frac{1}{|\mathbf{R}|^{3}}}} term falls quickly.
The coordinates of a point r in an n-dimensional space are simply an ordered set of n numbers:r.{\displaystyle\mathbf{r}=.} In a general Banach space, these numbers could be(for example) coefficients in a functional expansion like a Fourier series.
One of the notable aspects of Bloch's theorem is that it shows directly that steady state solutions maybe identified with a wave vector k{\displaystyle\mathbf{k}}, meaning that this quantum number remains a constant of motion.
In fluid dynamics, Faxén's laws relate a sphere's velocity U{\displaystyle\mathbf{U}} and angular velocity Ω{\displaystyle\mathbf{\Omega}} to the forces, torque, stresslet and flow it experiences under low Reynolds number(creeping flow) conditions.
The normalized vector or versor û of a non-zero vector u is the unit vector in the direction of u, i.e., u^ u|u|{\displaystyle\mathbf{\hat{u}}={\frac{\mathbf{u}}{|\mathbf{u}|}}} where|u| is the norm(or length) of u.
The time derivative of the integral for work yields the instantaneous power, d W d t P( t) F⋅ v.{\displaystyle{\frac{ dW}{ dt}}= P(t)=\ mathbf{F}\cdot\mathbf{v}.} If the work for an applied force is independent of the path, then the work done by the force, by the gradient theorem, defines a potential function which is evaluated at the start and end of the trajectory of the point of application.
A consequence of this potential energy function is that it is possible to shift the initialposition of an electron by any lattice vector a{\displaystyle\mathbf{a}} without changing any aspect of the problem, thereby defining a discrete symmetry.
In classical mechanics, the angular momentum of a particle can be reinterpreted as a plane element:L r∧ p,{\displaystyle\mathbf{L}=\mathbf{r}\wedge\mathbf{p}\,,} in which the exterior product∧ replaces the cross product× these products have similar characteristics but are nonequivalent.
A common method of modeling crystal structure and behavior is to view electrons as quantum mechanical particles traveling through a fixed infinite periodic potential V( x){\displaystyle V(x)} such that V( x+ a) V( x),{\displaystyle V({\mathbf{x}}+{\mathbf{a} })=V({\mathbf{x}}),}where a{\displaystyle\mathbf{a}} is an arbitrary lattice vector.
Therefore, there exists a contact force density or Cauchy traction field T( n, x, t){\displaystyle\mathbf{T}(\mathbf{n},\mathbf{x},t)} that represents this distribution in a particular configuration of the body at a given time t{\displaystyle t\,\!
Using the center of mass and inertia matrix, the force and torque equations for a single rigid body take the form F m a,T α+ ω× ω,{\displaystyle\mathbf{F}=m\mathbf{a},\quad\mathbf{T}=\alpha+\omega\times\omega,} and are known as Newton's second law of motion for a rigid body.
The measured intensity of the reflection will be square of this amplitude A 2 S 2| F( q)| 2.{\displaystyle A^{ 2} S^{ 2}\ left|F(\ mathbf{q})\right|^{2}.} For every reflection corresponding to a point q in the reciprocal space, there is another reflection of the same intensity at the opposite point-q.
The momentum that is physical, the so-called kinetic momentum(used throughout this article), is(in SI units) p m v P-e A{\displaystyle\mathbf{p}=m\mathbf{v}=\mathbf{P} -e\mathbf{A}} where e is the electric charge of the particle and A the magnetic vector potential of the electromagnetic field.
If τ{\displaystyle\tau} is a quadratic irrational, then the j-invariant is an algebraic integer of degree| Cl( Q( τ))|{\displaystyle|{\ mbox{ Cl}}(\ mathbf{Q}(\tau))|}, the class number of Q( τ){\displaystyle\mathbf{Q}(\tau)} and the minimal(monic integral) polynomial it satisfies is called the Hilbert class polynomial.
The sum of these small amounts of work over the trajectory of the rigid body yields the work, W∫ t 1 t 2 T⋅ ω→ d t.{\displaystyle W=\int_{ t_{ 1}}^{ t_{2}}\ mathbf{T} \cdot {\vec {\omega}}dt.} This integral is computed along the trajectory of the rigid body with an angular velocity ω that varies with time, and is therefore said to be path dependent.
