All four fundamental forces; gravity, electromagnetism, weak nuclear, and strong nuclear, propagate in a vacuum, however their respective effectual distances vary greatly.
if the distance is infinite then the force between them is practically zero. they vary inversely
The gravitational force between the Earth and sun certainly depends on the distance between the Earth and sun. But the gravitational force between, for example, the Earth and me does not.
The gravitational force on an object at a standard distance is proportional to the mass of the planet.
The gravitational force on an object at a standard distance is proportional to the mass of the planet.
The gravitational force on an object at a standard distance is proportional to the mass of the planet.
All attractive forces, gravitational, coulombic, and magnetic vary as the square of the distance between two objects. Thus, as the distance increases, the force between them becomes much weaker and weaker.
"Chemical reaction rates vary with the conditions of the change but nuclear rates do not."
the closer the magnet is to the nails the greater the magnetic force between the magnet and the nails
Two factors affect the gravitational attraction between objects: mass and distance.
Fe = kq1q2 / r2 where k = 1/4πε, (ε is the electrical permittivity of free space), q1 and q2 are the two point charges, and r is the distance between the point charges. Therefore, electrical force varies inversely with distance, or to be more specific, they follow an inverse-square relationship.
The distance between the above places is 9 miles. This distance is point to point straight distance as seen on the map. The actual distance covered by a flight may vary according to the flight path chosen. Also this is not the airport to airport distance.
