How Gravity Works

If you’ve ever wondered why what goes up suddenly tends to come down and what makes them come down, then you’ve witnessed gravity at work. However, that is not all to gravity as we once thought. If you want to know how gravity works, you have to consider why there is such a thing as gravity and what it seeks to achieve.

Over the years, we have been told that what goes up must always come down, this is referred to as what we now know to be gravity. However, this stand-alone definition is not quite far from the truth.

Gravity works like a pulling force (or a force of attraction) that occurs between every object matter and every other object in the universe! You can describe it as a magnetic pull between every matter towards each other, but it is what we know as gravitational force.

 

HOW GRAVITY WORKS ON EARTH

Earth sure does have a lot of gravity working in it. This explains why everything that is on earth tends to stay on it. To know how gravity works, look at everything around you. They are all happening on earth. Gravity is that force that will tend to keep everything you can think of down to earth.

Gravity does a good job of pulling everything on earth (atmosphere inclusive) towards it. That is why there’s a phenomena such as air pressure and water pressure. To avoid the continuous drawing of all things towards itself and possibly to the core of the earth, there are forces that help to keep gravity itself in check.

These forces balance the downward pull of gravity and help to keep every matter balanced. A car will not get sucked into the Earth’s core because as the force of gravity tend to pull the car further to the earth, the atoms surrounding the car balance it by pushing it upwards. That’s why it can comfortably stay on its four wheels without getting sucked in. So there is an upward force counteracting the downward pull of gravity.

 

HOW GRAVITY WORKS IN SPACE

Gravity works a bit differently in space. Gravity works by pulling every bit of matter in space towards its center. This explains why the planets constantly orbit around the sun. They are held together by a force of gravity that keeps them in continuous orbital motion. Gravity is responsible for how asteroids move and how much impact they have on planets.

The force of gravity enables humans to send satellites and spacecraft into space and have them return after the voyage. It is a fundamental force-keeping phenomenon occurring at all times in space.

 

Gravity is created by any object or thing that has matter. The gravitational pull of the Sun and other planetary bodies reach far out in space. The influence of gravity, on the other hand, diminishes with an increase in distance. The gravity exerted on a single object may be nearly zero at far distances, even though it can never be absolutely removed.
