Speed as a Rate of Change (HSC SSCE Mathematics Advanced): Flashcards

Rate of change of distance with respect to time

Scalar (magnitude only)

Vector (has magnitude and direction)

Always ≥ 0 (non-negative)

$\frac{\Delta d}{\Delta t} = \frac{d(t_2) - d(t_1)}{t_2 - t_1}$

Average speed over that interval

Constant speed

Varying/changing speed

Zero speed (stationary)

Higher speed
