Gravity is the force that pulls all elements of matter together. Matter refers to things you can physically touch. The more matter there is, the greater the amount of gravity or force. This means that the Earth or other planets have a great deal of pull and that everything on Earth is pulled back to Earth.
Gravity is the mutual atraction of two bodies in the universe. Since gravity refers to an invisible force pulling matter together, there are many examples of gravity. Every single thing has gravity, including people.
Some objects have much more gravity than others. The Earth, for example, has more gravity than people. This is why an object that falls is drawn to the Earth and returns to the Earth instead of being drawn to a person and flying at that person.
Some examples of the force of gravity include:
Gravity has the same effect on every object. If you drop a huge elephant or if you drop a small, thin feather, they will fall at the exact same speed. The feather might look like it falls slower and it does because there is air resistance that interferes with the force of gravity and that can slow it down. However, if you dropped a feather and an elephant in a vacuum where there was no air resistance, they'd fall at the exact same speed because there is the exact same amount of force being exerted.
By reviewing examples of gravity, you can better understand gravity and how it works in a variety of situations.
