Velocity of a body accelerating / decelerating with a constant acceleration \(a\).
Velocity that the body had at the initial time before it started to accelerate.
Current position (e.g. end position) of the body on the \(x\) axis.
Initial position of the body on the \(x\) axis before it started to accelerate. The difference between the current position and the initial position is the distance traveled: \( s = x - x_0 \).
Constant (fixed) acceleration of the body.
