WebGravitational force F_g F g is always attractive, and it depends only on the masses involved and the distance between them. Every object in the universe attracts every other object with a force along a line joining them. The equation for Newton’s law of gravitation is: F_g = \dfrac {G m_1 m_2} {r^2} F g = r2Gm1m2 Where: WebA simple pendulum has a time period of 1.42 s on Earth.
