Kinematic Equations in x-Direction

Reference from the original Physics I textbook.

For constant x-acceleration, using signed scalar components:
x = x₀ + v₀ₓΔt + ½aₓ(Δt)²;
vₓ² = v₀ₓ² + 2aₓΔx;
vₓ = v₀ₓ + aₓΔt;
x = x₀ + ½(vₓ + v₀ₓ)Δt.

$x = Final x-position (m)$
$x_{0} = Initial x-position (m)$
${\vec{v}}_{0, x} = Initial x-Velocity (m/s)$
$Δ t = Time (s)$
${\vec{a}}_{x} = {Acceleration in the x-direction (m/s}^{2})$
${\vec{v}}_{x} = Final x-Velocity (m/s)$

Kinematics
Kinematics describes motion using position, velocity, acceleration, and time without first analyzing its forces. The familiar constant-acceleration equations apply only over intervals in which that acceleration is constant. For example, a ball falling near Earth with negligible air resistance can be modeled with constant vertical acceleration.
