WebTo take the derivative of a vector-valued function, take the derivative of each component. If you interpret the initial function as giving the position of a particle as a function of time, the derivative gives the velocity vector of that particle as a function of time.

WebElectric potential energy is a property of a charged object, by virtue of its location in an electric field. Electric potential energy exists if there is a charged object at the location. Electric potential difference, also known … Webwhere φ ( r, t) is the electric potential and A ( r, t) is the magnetic vector potential, for an arbitrary source of charge density ρ ( r, t) and current density J ( r, t ), and is the D'Alembert operator. [2] Solving these gives the retarded potentials below (all in SI units ). For time-dependent fields [ edit]
http://insti.physics.sunysb.edu/itp/lectures/01-Fall/PHY505/09c/notes09c.pdf In vector calculus, a vector potential is a vector field whose curl is a given vector field. This is analogous to a scalar potential, which is a scalar field whose gradient is a given vector field. Formally, given a vector field v, a vector potential is a vector field A such that
WebIf F is a conservative vector field (also called irrotational, curl -free, or potential ), and its components have continuous partial derivatives, the potential of F with respect to a reference point r0 is defined in terms of the line integral : …
