Impulse (Grade 12 NSC Matric Physical Sciences): Quizzes

$F_{\text{net}} \times \Delta t$

$\text{N} \cdot \text{s}$ or $\text{kg} \cdot \text{m} \cdot \text{s}^{-1}$

Change in momentum ($\Delta p$)

Small

To increase collision time and reduce force

Impulse delivered to the object

$20 \text{ N} \cdot \text{s}$

$24 \text{ N} \cdot \text{s}$

Negative impulse

$2 \text{ s}$
