Answer:
inertia and gravitation
Step-by-step explanation:
Hi, he produced the law of inertia and gravitation.
Newton's law of universal gravitation is about the universality of gravity.This force of gravitational attraction is directly dependent upon the masses of both objects and inversely proportional to the square of the distance that separates their centers.
Newton's First Law ( also known as the law of inertia) states that an object will remain at rest or in uniform motion in a straight line unless acted upon by an external force.
