Question

The Principle of Conservation of Linear Momentum is presented as a direct consequence of which fundamental law of motion?

Options

• Newton's law of universal gravitation

• Newton's third law

• Newton's second law

• Newton's first law

Answer 1

Newton's second law

Explanation:

The net force equals the rate of change of momentum (F = dp​/dt). If F = 0, it follows directly that dp​/dt = 0, meaning momentum p​ is constant.
