Description

A 5-step lesson. Step 1: 'Momentum (p) = mass × velocity. p = mv. Units: kg·m/s. Momentum is a VECTOR (has direction).' Step 2: 'Newton's Second Law rewritten: F = Δp/Δt (force equals rate of change of momentum). This is actually Newton's original formulation!' When mass is constant: F = m(Δv/Δt) =
