Universal Law of Gravitation Simulation

What is the Universal Gravitational Law?

• The force of gravity is equal to the mass of an object.

• The magnitude of the Gravitational force that an object exerts on another is directly proportional to the product of their masses and inversely proportional to the square of the distance between them.

• Gravity is a force that only acts on objects with mass greater than 1 kg.

• The gravitational force is a constant value for all objects regardless of their mass and distance.

What is the value of the universal gravitational constant, G?
