This wave-induced mass transport is caused by the positive correlation between surface elevation and horizontal velocity.
Assuming air resistance does not do anything extreme, the projectile will continue with this horizontal velocity because gravity cannot change it.
The projectile never gets any horizontal velocity because gravity can't change it.
However, the largest horizontal velocity is found near the former ice margin.
At the same moment, General Bellmon decided he had sufficient horizontal velocity and needed next a little altitude.
The airfoil is modelled as a flat plate in a potential flow, moving with constant horizontal velocity.
He would therefore have to rely upon the wind itself to reduce his horizontal velocity.
The 2D vector (u,v) is the fluid's horizontal velocity, averaged across the vertical column.
It increases our rate of drop but increases our horizontal velocity.
The horizontal velocity of the balloon would generally increase with altitude and become more easterly.
