|---|---|---|---|---|---|
| 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
🗑
|
||||
| Oort cloud | A big shell of icy bodies that surrounds the solar system well beyond pluto
🗑
|
||||
| Solar wind | Particles that push away from the sun causing a "wind"
🗑
