Sir Isaac Newton is deemed as one of the most prominent scientists who contributed immensely to the scientific revolution. Scientific revolution period established a foundation in which the modern science is solely based on. Sir Isaac Newton was an English astronomer, physicist, and mathematician. Some of Sir Isaac Newton’s contributions to science and mathematics include, the discovery of gravity, came up with the laws of motion and co-developed calculus.
Theory of gravity
Newton’s law of universal gravitation states that every mass attracts every other mass in the universe, and the gravitational force between two bodies is proportional to the product of their masses and inversely proportional to the square of the distance between them.

The theory of gravity asserts that the shape of the stars and the planets is spherical, Newton concluded that mass of spherical objects is concentrated at the center. Hence, he argued that the distance between any two or more spherical objects should include the distance to the center of the objects. Newton explained that the force of gravity is always attractive, it functions instantaneously at a particular distance and bears a range which is infinite. Most significantly, it affects everything that has mass. Newton further stated that the force of gravity is not affected by the object’s chemical composition or its charge.
This explanation can be used to explain the downward force originating from the earth’s pull as stated by Galileo. This explanation also aligns with Kepler’s explanation of why the planets orbit around the sun.
When you combine Newton's theory of gravity with his second law of motion, it explains why objects with distinct masses fall at the same rate. This is because objects acceleration due to gravity only depends on the mass of the object that is pulling it.
