Momentum & Impulse (Edexcel A-Level Further Mathematics): Flashcards

$p = mv$

Vector quantity

$J = F\Delta t$

$J = mv - mu$

$F\Delta t = mv - mu$

Total momentum before = total momentum after

$m_1u_1 + m_2u_2 = m_1v_1 + m_2v_2$

No external forces acting

Equal magnitude, opposite direction

Opposite to initial direction of motion
