Explanation:

Newton's first law of motion states that an object at rest stays at rest and an object in motion stays in motion with the same speed and in the same direction unless acted upon by an unbalanced force. This is also known as the law of inertia. Newton's second law is about the relationship between force, mass, and acceleration ($F = ma$). Newton's third law is about action - reaction pairs. The law of universal gravitation is about the gravitational force between two objects ($F=\frac{Gm_1m_2}{r^{2}}$).

Answer:

Newton's first law of motion
