Explosions

In an explosion momentum must be conserved.total initial momentum = 0Total final momentum = 0Objects recoil from each other with equal and opposite amounts of momentum and since momentum is a vector quantity p₁ + p₂ + p₃...+ p_n = 0In other words the vector sum of the momentum of all the individual pieces is zero.This means the pieces have to fly in different directions. Σp_initial = Σp_final = 0(Momentum is always conserved in all types of collisions and explosions).
