Gravity is a force between materials. The greater the mass, the greater the force of gravity, so things that have a lot of mass, such as the planet Earth, pulls things with less mass, such as a chunk of rock, to its surface. As shown in the diagram, the winner of the gravity tug-of-war between [...]

The gravity diagram models the action-reaction forces of gravity between Earth and a person. While the forces are equal the masses of two objects vary greatly, with Earth being the winner with the larger mass.

  What is Gravity? How is Gravity Measured? Gravity is the force of attraction between two bodies due to their mass and distance from each other. The magnitude of the gravitational force between two objects can be determined using the following equation: Newton’s Equation for the Force of Gravity F = G x m1 x [...]
