Question
gravitational force
gravity & distance
the greater the distance between two objects, the less gravitational force there is.
- the suns gravitational force is greater than earths gravitational force because it has more mass.
however, the moon orbits earth because it is much closer to earth than it is to the sun.
what would have more gravitational force between them? explain.
earth and mars
or
earth and pluto
Gravitational force depends on the masses of objects and the distance between them, following the inverse-square law: gravitational force increases with greater mass and decreases with greater distance. Mars has more mass than Pluto, and Mars is much closer to Earth than Pluto is. Both factors (closer distance and greater mass of Mars relative to Pluto) mean the gravitational force between Earth and Mars is stronger.
Mars is closer to Earth than Pluto, and Mars has a greater mass than Pluto. Since gravitational force is stronger when objects are closer and have more mass, the gravitational force between Earth and Mars is greater than that between Earth and Pluto.
