Delta-v

In general physics, delta-v is simply the change in velocity.

Depending on the situation delta-v can be referred to as a spatial vector (Delta mathbf{v},) or scalar (Delta{v},). In both cases it is equal to the acceleration (vector or scalar) integrated over time:

~ ~ ~ ~ ~ ~ ~ ~ ~ ~

~ ~ ~ ~ ~ ~ ~ ~ ~ ~

:Delta mathbf{v} = mathbf{v}_1 - mathbf{v}_0 = int^{t_1}_{t_0} mathbf {a} , dt (vector version)

~ ~ ~ ~ ~ ~ ~ ~ ~ ~

:Delta{v} = {v}_1 - {v}_0 = int^{t_1}_{t_0} {a} , dt (scalar version)

~ ~ ~ ~ ~ ~ ~ ~ ~ ~

where:

~ ~ ~ ~ ~ ~ ~ ~ ~ ~

• $mathbf\{v\_0\},$ or $\{v\_0\},$ is initial velocity vector or scalar at time $t\_0,$,
• $mathbf\{v\_1\},$ or $\{v\_1\},$ is target velocity vector or scalar at time $t\_1,$.

Spatial vector: REDIRECT Euclidean vector...

Acceleration: In physics, acceleration (symbol: a) is defined as the rate of change (or time derivative) of velocity. It is thus a vector quantity with dimension length/time². In SI units, this is meter/second²....
