What is the gravitational force
gravity | Definition, Physics, & Facts | Britannica
G is a number called the “Gravitational Constant”, which relates the gravitational force in Newtons to the masses in kilograms and the distance in meters. Its value is 6.67 x 10-11 Nm2 /kg2 . This value is extremely small, so the gravitational attractive force between two objects, like your body and a baseball, is so small that it goes ...

A prime example of an invisible force is the gravitational force – the attraction of the Earth for objects. When an object falls close to the surface of the Earth, there is no obvious force being applied to it. Whatever is causing the object to move is invisible. Most people rather casually refer to the cause of falling motions as the action ...

Calculate the distance between the center of the earth and the center of the moon at which the gravitational force exerted by the earth on an object is equal in magnitude to the force exerted by the moon on the object. ANSWERS: 1. 500 - 900 N (at 65kg, 638N) 2. 0 N (at 65kg, the gravitational force would be 564N) – 11.5% less.
