Question

What principle is confirmed if two molecules exert equal and opposite impulses, giving zero net impulse?

Options

• Newton's First Law (Inertia)

• Newton's Third Law (Action-Reaction)

• Law of Conservation of Energy

• Newton's Second Law (F = ma)

Answer 1

Newton's Third Law (Action-Reaction)

Explanation:

Since J = F × Δt, equal and opposite impulses imply equal and opposite average forces over the same time, which confirms Newton's Third Law.
