Speed and Velocity (Grade 10 NSC Matric Physical Sciences): Quizzes

$v_{av} = \frac{D}{\Delta t}$

Scalar quantity

No, speed is always positive

$\bar{v}_{av} = \frac{\Delta \bar{x}}{\Delta t}$

Vector quantity

Yes, depending on direction of motion

Speed depends on path; velocity doesn't

Zero velocity but non-zero speed

$0$ m·s⁻¹

Distance
