Gravitational force | Any objects that have the same mass are attracted to each other. It is also the weakest |
Electromagnetic force | Exsists between particles with a charge. Can be attracted or repulsive |
Weak force | Governs certain radioactive process in atoms |
Strong force | Responsible for holding the center of the atom together |
First Law of Gravitation | All objects with a mass are attracted to one another by the gravitational force |
Second Law of Gravitation | The gravitational force between two masses is directly proportional to the mass of each object |
Thrid Law of Gravitation | The gravitational force between two masses is inversely proportional to the square of the distance between those two objects |
Centripetal force | The 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 center of the circle |
First principle of Centripetal force | Circular motion requires centripetal force |
Second principle of Centripetal force | The larger the centripetal force, the faster an object travels in a circle of a given size |
Third principle of Centripetal force | At a given speed, the larger the centripetal force, the smaller the circle |
Short-period | An object that takes less than 200 years to make an orbit |
Long-period | Objects that take more than 200 years to orbit the sun |
Very long-period | Objects that take more than 5,ooo years to make one orbit |
Kuiper belt | A band that is 150-mile wide body |
