Uniform Acceleration

Characteristics of Uniform Acceleration

Value of velocity changes in time linearly
Acceleration ≠ 0, it can be positive (accelerated) or negative (decelerated)

Formula

$\begin{array}{lll} s = v_{o} . t + \frac{1}{2} . a . t^{2} & (1) \\ v_{t} = v_{o} + a . t & (2) \\ v_{t}^{2} = v_{o}^{2} + 2 . a . s & (3) \end{array}$

$s$ = distance (m)
$v_{o}$ = initial velocity (m/s)
$v_{t}$ = final velocity (m/s)
$a$ = acceleration (m/s²)
- Accelerated $a = (+)$
- Decelerated $a = (-)$
$t$ = waktu (s)
