Momentum (Edexcel GCSE Physics Combined Science): Flashcards

Property of all moving objects

Zero

$p = m \times v$

$kg m/s$ or $kgms^{-1}$

Momentum

Total momentum before = total momentum after in closed system

In collisions/explosions with no external forces

Vector

Force = rate of change of momentum

$F = \frac{(mv - mu)}{t}$

$mv$ = final momentum, $mu$ = initial momentum
