Physical constraints and practical limitations of differential equation models, such as resistance laws failing at high speeds or capacity constraints.
Where predictions diverge from reality, such as P(t) → ∞ as t → ∞, which is physically impossible.
Binomial needs independence and constant probability; Normal needs symmetry and a suitable scale.
