Velocity was launched by Virgin Blue (later renamed Virgin Australia) in 2005 as Velocity Rewards, with partner National Australia Bank offering a companion credit card. [1] Initially, Velocity differed from most other frequent flyer programs with points earned being based on the cost of a flight, rather than distance.
In aviation, a variometer – also known as a rate of climb and descent indicator (RCDI), rate-of-climb indicator, vertical speed indicator (VSI), or vertical velocity indicator (VVI) – is one of the flight instruments in an aircraft used to inform the pilot of the rate of descent or climb. [1]
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 mechanics that describes the motion of bodies. Velocity is a physical vector quantity: both magnitude and direction are needed to define it.
The dashed lines represent contours of the velocity field (streamlines), showing the motion of the whole field at the same time. (See high resolution version.) Solid blue lines and broken grey lines represent the streamlines. The red arrows show the direction and magnitude of the flow velocity. These arrows are tangential to the streamline.
Escape speed at a distance d from the center of a spherically symmetric primary body (such as a star or a planet) with mass M is given by the formula [2] [3] = = where: G is the universal gravitational constant (G ≈ 6.67×10 −11 m 3 ·kg −1 ·s −2)
President-elect Donald Trump claimed during a Dec. 16 press conference at his Mar-a-Lago residence that he won the youth vote by 34 points in the 2024 presidential election. Verdict: False Both ...

The expression "1 g = 9.806 65 m/s 2 " means that for every second that elapses, velocity changes 9.806 65 metres per second (35.303 94 km/h). This rate of change in velocity can also be denoted as 9.806 65 (metres per second) per second, or 9.806 65 m/s 2.
