Momentum (VCE SSCE Physics): Flashcards

$p = mv$

$ext{kg} cdot ext{m} cdot ext{s}^{-1}$

Vector quantity

Total $p$ before = total $p$ after (closed system)

No external forces; no mass/energy transfer

Total KE before = total KE after

Total KE after < total KE before

Change in momentum

$Delta p = F_{ ext{av}}Delta t = mv - mu$

Impulse
