Physics pt. 4: Gravity

Gravity is pretty cool, as it helps pull objects together, it attracts things to the floor, so if there's a ball flying through the air, the gravitational force is pulling it down so it doesn't go into space.

It is an attractive force, as it exists for everything that has mass, first of all, what is mass, well mass is how much stuff an object is made of.'

Gravity will be different for things that are made of different mass, and distance, as the heavier or more mass something is the faster it falls, or the stronger the gravitational force.

The Earth itself is nearly six septillion kilograms, that's a six with 24 zeros after or (6,000,0000,0000,0000,0000,0000,0), for scale a cat usually weighs about 4 kilograms.

That is just one reason that affects the gravitational force, the other is the distance, the closer an object is to the gravitational force, the weaker it is, so us being on the ground you barely feel the forces pulling you down, the only way to not feel the gravitational force of the Earth is to go REALLY far away, or Outer Space.
Take a look at the moon, it is nearly 400,000 kilometres away from Earth, and it is still affected by Earth's gravity, but since the moon is really far away, and it is also big, you can also feel the gravitational pull it, and that's why ocean Tides exists as the moon is pulling the water which causes high and low tides.

But how can we walk around and not feel any sort of strain and not face planted dragging ourselves around, well it's because we only notice the strength of it when it is a really big planet or star, and the gravitational pull on you dragging you down is much weaker compared to the forces you use every day, let's say you pick up a ball or a glass of water, since the gravitational force pulling the water down, if you pick up the glass of water you are overpowering the gravitational pull of the Earth to pickup that water and move it to your mouth.
