In celestial mechanics, escape velocity or escape speed is the minimum speed needed for an object to escape from contact with or orbit of a primary body...

A zero-velocity surface is a concept that relates to the N-body problem of gravity. It represents a surface a body of given energy cannot cross, since...

Terminal velocity is the maximum speed attainable by an object as it falls through a fluid (air is the most common example). It is reached when the sum...

dependent on the velocity of the surface of the Earth where it is located. The point of connection of the pendulum moves with the surface velocity vectors of...

surface velocity of solids moving at high speeds. For solids experiencing high velocity impact or explosive conditions, VISAR plots the free-surface velocity...

Velocity is the speed in combination with the direction of motion of an object. Velocity is a fundamental concept in kinematics, the branch of classical...

bounding surface formed by the fluid flowing along the surface. The fluid's interaction with the wall induces a no-slip boundary condition (zero velocity at...

two fluid layers, two solid surfaces, or between a fluid and solid surface. Drag forces tend to decrease fluid velocity relative to the solid object...

the phase velocity. A sinusoidal wave, of small surface-elevation amplitude and with a constant wavelength, propagates with the phase velocity, also called...

hyper-velocity or short-ranged missiles may use body lift or fly a ballistic trajectory. The V-1 flying bomb was the first operational surface-to-surface missile...

from such a gun on the surface of the body would leave its gravitational field; however, no arms are known with muzzle velocities that can overcome Earth's...

evolution of the surface Σ {\displaystyle \Sigma } indexed by a time-like parameter t {\displaystyle t} . The definitions of the surface velocity C {\displaystyle...

the bullet's surface can increase its diameter enough to either prevent insertion of the cartridge into the chamber, or – with high velocity rounds – cause...

The phase velocity of a wave is the rate at which the wave propagates in any medium. This is the velocity at which the phase of any one frequency component...

The group velocity of a wave is the velocity with which the overall envelope shape of the wave's amplitudes—known as the modulation or envelope of the...

where v = flow velocity, A = cross-sectional vector area/surface. The above equation is only true for uniform or homogeneous flow velocity and a flat or...

are typically called SVP drifters because they were developed by the Surface Velocity Program (SVP) of the Tropical Ocean Global Atmosphere (TOGA) experiment...

{\boldsymbol {\omega \times v}}} This component is orthogonal to the velocity over the Earth surface and is given by the expression ω v   2 sin ⁡ ϕ {\displaystyle...

sources. The propagation velocity of a seismic wave depends on density and elasticity of the medium as well as the type of wave. Velocity tends to increase with...

t}}=w'\left(0\right),\,} where the velocity w ′ ( η ) {\displaystyle \scriptstyle w'\left(\eta \right)\,} is linearized on to the surface z = 0. {\displaystyle \scriptstyle...
