Position

<x(t), y(t)>

Velocity

<V_x(t), V_y(t)> or <x’(t), y’(t)>

Acceleration

<V_x’(t), V_y’(t)> or <x’’(t), y’’(t)>

Displacement

$\int_{a}^{b}\vec{v}(t)dt$ or $\Delta x = \int_{a}^{b}V_x(t)dt; \Delta y = \int_{a}^{b}V_y(t)dt$

Speed

$|\vec{v}(t)|$ or $\sqrt{(x’(t))^{2}+(y’(t))^{2}}$ or$\sqrt{(V_x(t))^{2}+(V_y(t))^{2}}$

Distance

$\int_{a}^{b}\text{speed } dt$; $\int_{a}^{b}|\vec{v}(t)|dt$ or $\int_{a}^{b}\sqrt{(V_x(t))^{2} + (V_y(t))^{2}} dt$
