Equations and live substitution

Object momentum: p = m × v

Total momentum: pₜ = m₁ × v₁ + m₂ × v₂

Conservation: total momentum before = total momentum after

Impulse: J = change in momentum = F × Δt

Kinetic energy: KE = ½ × m × v²

Joined velocity: v = (m₁u₁ + m₂u₂) ÷ (m₁ + m₂)

p = m × v

Direction matters. Rightward momentum is positive and leftward momentum is negative in this laboratory.
