Priniciple 1of Gravitational ForceAll objects with mass are attracted to one another by the gravitational force.
Principle 2 of Gravitational ForceThe gravitational force between two masses is directly proportional to the mass of each object.
Principle 3 of Gravitational ForceThe gravitational force between two masses is inversely proportional to the square of the distance between those two objects.
Principle 1of Centripetal ForceCircular motion requires centripetal force.
Principle 2 of Centripetal ForceThe larger the centripetal force, the faster an object travels in a circle of a given size.
Principle 3 of Centripetal ForceAt a given speed, the larger the centripetal force, the smaller the circle.
Centripetal ForceThe force necessary to make an object move in a circle. It is directed perpendicular to the velocity of the object, which means it points toward the centre of the circle.
