# Gravity: Facts on Gravity

### Fun Facts on Gravity:

Gravity is defined as a natural force that pulls a body towards the center of the earth. It is also defined as a force that pulls a physical body with a lesser mass to another having a greater mass.

An instance of the effects of gravity is seen between the moon and earth. Since the moon has a lesser mass than the earth, it will be pulled towards the earth as a result of gravity. Similarly, the earth which is smaller in size when compared to the sun will be pulled towards it as a result of gravity (or gravitational force).

A good knowledge on the concept of gravity will aid you to better comprehend the facts surrounding gravity.

Below are some interesting fact concerning gravity:

1. Your weight changes as you travel away from the earth.

2. The human body begins to malfunction when gravity is not present. This is true because we will begin to float in the absence of gravity. Consequently, the muscles and bones becomes weaker since they are not utilized.

3. In a vacuum (a space completely empty of matter), if you dropped a ball and a feather simultaneously from the same height, they will both land at the exact same time as a result of gravity. Gravity therefore moves all things at the same rate provided the environment has no matter in it.

4. If we dig the earth until we get into its center, we will have no weight as a result of lack of gravity. Always understand that weight is a function of gravity; and a condition of having no weight is termed weightlessness.

5. Although the earth rotates and we are on it, we will not fall off it. This is so because because gravity is a force that always pull us towards the surface of the earth. Aircrafts are able to leave the earth's surface because they generate a force greater than gravity.

6. Sir Isaac Newton was not hit by an apple as shown in many pictures. He only pondered if the force that made apples fall actually involves the movement of the moon around the earth.

7. The force of gravity is generally considered the weakest force among the four forces that govern the universe. The three other forces are:

8. You will weigh more on Jupiter than on earth because of its size. The bigger the size, the larger the force of gravity.

9. Spinning an object can create artificial gravity.
