Momentum and Impulse (Grade 12 NSC Matric Physical Sciences): Flashcards

Momentum will not change

Net force = rate of change of momentum

$\bar{F}_{\text{net}} = \frac{\Delta\bar{p}}{\Delta t}$

$\bar{F}_{\text{net}} = m\bar{a}_{\text{net}}$

Vector quantity (direction is crucial)

$\Delta\bar{p} = m\bar{v}_f - m\bar{v}_i$

Identify information given and convert to SI units

Must be consistent throughout calculations

Both magnitude and direction

Mass in kg, velocity in m·s⁻¹
