Describing Motion Using Vectors (HSC SSCE Physics): Flashcards

Divide displacement by time

Vector quantity

$\vec{v} = \vec{v}_x + \vec{v}_y$

$v = \sqrt{v_x^2 + v_y^2}$

$v_x = v\cos\theta$

$v_y = v\sin\theta$

$\tan\theta = \frac{v_y}{v_x}$

$\Delta\vec{v} = \vec{v}_f - \vec{v}_i$

$\vec{a} = \frac{\Delta\vec{v}}{t}$

No, they have different units
