Momentum formula

p=m×vp = m \times v

Units of momentum

kgm/skg m/s or kgms1kgms^{-1}

What pp stands for in momentum formula

Momentum

Conservation of momentum in closed system

Total before = total after event

When is momentum always conserved

Collisions/explosions without external forces

Type of quantity: momentum

Vector

Newton's 2nd Law (momentum)

Force = rate of change of momentum

Force formula using momentum

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

In F=(mvmu)tF = \frac{(mv - mu)}{t}, what is mvmv

Final momentum

In F=(mvmu)tF = \frac{(mv - mu)}{t}, what is mumu

Initial momentum
