# Examples of Force of Gravity

## Force of gravity

The force of gravity is the attraction that two bodies exert on each other. This is generated because of the mass between the two, this means that the greater the mass of a body, the greater the force it exerts on other bodies.

This concept applies to all living or inert objects in the universe . The moon’s gravity is much less than that of the Earth because it has a lower mass, however, Jupiter has a much greater mass, its attractive force is greater. Apart from this, it is known that this is one of the weakest forces in nature and this is because in order to exert gravity a large amount of mass is needed in a single object , however, the force can be felt through billions of miles away.

### Gravity in the universe

The gravity is something we can experience in every aspect of our lives, being able to walk from one side to another is clear indication of the gravity of the Earth and can even jump or throw objects on the ground which would not be possible without this force. On our planet the gravitational field is an acceleration of 9.81 meters per second squared, with this data it can be said that if an object falls from a certain height it will increase its speed by 9.81 meters per second.

The now known as the law of gravity or theory of gravity was proposed by Isaac Newton who points out that every body that has mass exerts gravitational attraction on any other object with mass, regardless of the distance between them, the greater the the greater the attraction. On the other hand Albert Einstein is another of the scientists who studied gravity to which he referred in his theory of relativity.
