Variable Acceleration - 1D (Edexcel A-Level Mathematics): Flashcards

How far from origin (direction matters)

Rate of change of displacement (direction matters)

Speed: direction doesn't matter; velocity: direction matters

$v = \frac{ds}{dt}$

$a = \frac{dv}{dt}$

$a = \frac{d^2s}{dt^2}$

When $v = 0$

When $v = 0$

$v = 0$

Displacement: $s = \int v \, dt$

Use initial conditions (given $t$ and $s$ values)

Particle is stationary ($v = 0$)

$\frac{dv}{dt} = 0$
