KEY CONNECTIONS

Formulas

S = v t

S = vt

S = \frac{v _{0} + v}{2} t

S = (v₀ + v)t / 2

S = v_{0} t \pm \frac{a t ^{2}}{2}

S = v₀t ± at²/2

S = \frac{v ^{2} - v _{0} ^{2}}{\pm 2 a}

S = (v² − v₀²) / (±2a)

S_{torm} = \frac{v _{0} ^{2}}{2 μ g}

Storm = v₀² / (2μg)

NOTATION

$S$: Distance - the length of the space between selected points.
$v$: Speed is the speed and direction of change in body position.
$t$: Time is a quantity characterizing the duration and sequence of events.
$v_0$: Initial speed - the speed of the body at the selected initial moment.
$a$: Acceleration is the rate of change in the speed of a body.
$S_{\text{torm}}$: Braking distance is the distance covered from the start of braking to stopping.
$\mu$: Friction coefficient is a characteristic of the resistance to movement of contacting surfaces.
$g$: Gravity acceleration is the acceleration of a body under the influence of gravity without taking into account the resistance of the medium.
