Isaac Newton with his law of universal gravitation is perhaps best known for explaining gravity, however in modern physics gravitation is described using Albert Einstein's general theory of relativity.

Newton summarized his ideas about gravity in a law now known as the law of universal gravitation. <3333333333 answered by JULIE A.
Gravity is what sets the planets in motion. The force that keeps them in motion is known as inertia in the law of physics.
By using the law of gravity and the laws of motion. The force of gravity is given by a mathematical formula: F = G.M1.M2 / R^2 The force is deduced from the Earth's sideways acceleration in its orbit. The mass of the Earth is known from the force of its attraction on a standard mass. The size of the Earth and its orbit are known from other measurements. So the only unknown in that equation above is on of the two masses, so it can be calculated.
The period to rotate once on its axis is known as a day,The period to revolve around the Sun is known as a year.
The theoretical movement of an object in a straight line without any forces (gravity, friction, etc) affecting it.
for inventing the reflecting telescope and discovering the three standard laws of motion. He also discovered gravity whilst observing an apple as it fell from a tree.
An abstract, esoteric mathematical operation known as "division." Divide mass by density, and you get volume. A note for purists: Technically speaking, specific gravity is not density, it is a ratio of densities. However, since one of the materials in the ratio is water, and its density is well known, it's easy to calculate the density of a material from its specific gravity.
