• Gravitational Force Calculator - Calculate the gravitational force in newtons (N) between any two objects by inputting the mass of the objects in kilograms (kg) as well as the distance between the objects in meters (m). What is the gravitational force between two people? Two elephants? Calculate the gravitational force between the Earth and a person on Earth. Is an astronaut really "weightless" when he or she is traveling in a spacecraft orbiting a few hundred kilometers above the Earth's surface? Calculate the answer to these and other weighty questions worth pondering (pun intended)....
