grav. through the Law of Gravitation enunciated by Newton in 1687. Every particle of matter in the universe attracts every other particle with a force that is directly proportional to the product of the masses of the particles and inversely proportional to the square of the distance between them.

Newton’s Law of Universal Gravitation. The gravitational acceleration, g depends on the distance, r, between the object and the earth’s center of mass. Equation (1) can be generalized for the gravitational force between two objects with masses m and M, for which M in eqn. (1)

The Force of Gravity (F G) Unlike the other forces above, which require contact, the force of gravity acts at a distance. The Sun and the Earth, or a book and the Earth, exert a force of gravity on one another without the objects having to be in direct contact. We will explore gravity in more detail later, but
Chapter 13 - Universal Gravitation. In Chapter 5 we studied Newton’s three laws of motion. In addition to these laws, Newton formulated the law of universal gravitation. This law states that two masses are attracted by a force given by.
We will use the Law of Universal Gravitation together with Newton's Laws of Motion to discuss a variety of problems involving the motion of large objects like the Earth moving in orbit about the Sun as well as small objects like the famous apple falling from a tree.

What are Newton's three laws of motion?
Gravity & Newton’s third law. Forces are pushes or pulls that act to change the shape or position of an object. Forces can be contact forces, such as: directly touching an object, friction between surfaces & drag as an object moves through a fluid. There are also non-contact forces, such as gravity, electrostatics & magnetism.
