What is Gravity?
Gravity is a fundamental force of nature that attracts two objects with mass towards each other. It is the force that holds us to the ground, keeps the planets in orbit around the sun, and creates the tides in our oceans. Gravity is one of the four fundamental forces of nature, along with the strong and weak nuclear forces, and electromagnetism.
The formal definition of gravity is that it is a force of attraction between two bodies that is proportional to the product of their masses and inversely proportional to the square of the distance between them. This means that the more massive an object is, the more gravity it will have and the closer two objects are, the stronger the gravitational force between them.
One example of gravity is the way that the Earth’s gravity pulls us towards it. This is why we can stand on the ground and why objects fall when they are dropped. Another example is the way that the Moon’s gravity causes the tides in the oceans. The Moon’s gravity is strong enough to pull the oceans towards it, creating high and low tides. Finally, gravity is also responsible for keeping the planets in their orbits around the sun. The sun’s gravity keeps the planets in their orbits, just like a giant sling shot.
