velocity

velocity

Speed of an object in a given direction, or how fast an object changes its position in a given direction. Velocity is a vector quantity, since its direction is important as well as its magnitude (or speed). For example, a car could have a speed of 48 kph/30 mph and a velocity of 48 kph/30 mph northwards. Velocity = change in position/time taken.

The velocity at any instant of a particle travelling in a curved path is in the direction of the tangent to the path at the instant considered. The velocity v of an object travelling in a fixed direction may be calculated by dividing the distance s it has travelled by the time t taken to do so, and may be expressed as: v = s/t

On the contrary he gazed joyfully, his eyes moist with tears, at this bright comet which, having traveled in its orbit with inconceivable velocity through immeasurable space, seemed suddenly- like an arrow piercing the earth- to remain fixed in a chosen spot, vigorously holding its tail erect, shining and displaying its white light amid countless other scintillating stars.
War and Peace by Tolstoy, Leo View in context
According to the advice forwarded from the members of the Observatory, the gun destined to launch the projectile had to be fixed in a country situated between the 0 and 28th degrees of north or south latitude, in order to aim at the moon when at the zenith; and its initiatory velocity was fixed at twelve thousand yards to the second.
