What does gravitational force depend on?
Gravitational force depends on mass and distance.
Therefore, the formula for calculating gravitational force among two objects with a given distance: G [(mass 1) (mass 2)]/distance squared. G is universal gravitational constant: 6.67x10 raised to -11 power.
How can electricity make magnetic fields? In 1820, Oersted discovered that an electric current can produce a magnetic field. He happened to notice a compass move when he conn
