Derive the equation for escape velocity. Escape Velocity: When an object is launched with enough speed, it can essentially make its way to space. This speed must be enough such that the gravitational effects of the planet is was launched from can be overcome. For Earth, we can have an esc...
" Yes, but I have assigned and applied that equation to a so-called orbital velocity, and we are studying a tangential velocity here. That is why Maxwell is doing tangents, you see. In other words, in my equation a=v2/2r, the v stands for orbital velocity, which I have shown is ...

First, in the case of the Schrödinger equation we have a dispersion of the phase velocity (Eq. (1.1.26)), cp = cp(ω) while for the wave equation cp = c0 = const. Second, since ω in the Fourier transform changes from -∞ to ∞, k2 appears to be negative for ω < 0 and ...
We say, “Let V be the velocity of a body through the aether”, and form the various electromagnetic equations in which V is scattered liberally. Then we insert the observed values, and try to eliminate everything which is unknown except V. The solution goes on famously; but just as we...

A Kinematic Equation is an equation that describes the motion of a vehicle based on its position, velocity, and acceleration without considering internal forces or energy, commonly used in path tracking controller research for defining vehicle motion. ...
Linear 3D wave functions are found exactly for eigenstates with an orbital momentum. In the case of self-repulsion, 3D wave functions are obtained by means of the Thomas-Fermi approximation. Then, with the help of the variational method, the underlying Gr...
However, profiles of water density allow the computation of the ocean's pressure and velocity field relative to reference pressure level. This has served oceanographers for many decades to study strength and vertical structure of the ocean circulation [15]. Besides observing ocean currents, the ...
